PRODUCT OVERVIEW

What Is the LT3093HDD#TRPBF?

LT3093HDD#TRPBF is an H-Grade high-performance negative low-dropout linear regulator from Analog Devices (Linear Technology) featuring the company's ultralow noise and ultrahigh PSRR architecture for powering noise-sensitive applications. The device supplies 200mA at a typical dropout voltage of 190mV, and can be easily paralleled to further reduce noise, increase output current, and spread heat on the PCB.

Operating quiescent current is nominally 2.35mA and drops to 3µA in shutdown. The LT3093's wide output voltage range of 0V to –19.5V, while maintaining unity-gain operation, provides virtually constant output noise, PSRR, bandwidth, and load regulation independent of the programmed output voltage. A single capacitor from SET to GND improves noise, PSRR, and transient response.

The regulator features a single-resistor programmable output voltage with a precision 100µA SET pin current (±1% initial accuracy), programmable current limit, fast start-up capability via the PGFB pin, and a programmable power-good indicator. A unique VIOC tracking function controls an upstream regulator to maintain a constant voltage across the LT3093, maximizing efficiency and PSRR while minimizing power dissipation. Built-in protection includes internal current limit with foldback and thermal limit with hysteresis.

The LT3093HDD#TRPBF is the H-Grade version in a thermally enhanced 12-lead 3mm × 3mm DFN package with an exposed pad. It is specified for operation from –40°C to +150°C junction temperature. The device is RoHS compliant, REACH unaffected, and in active production.

Ultralow Noise (–0.8µVRMS) 0.8µVRMS output noise (10Hz–100kHz) and 2.2nV/√Hz spot noise at 10kHz make this LDO ideal for powering noise-sensitive RF and precision analog circuits.

Ultrahigh PSRR & VIOC Tracking 73dB PSRR at 1MHz with virtually constant performance. The VIOC pin controls an upstream regulator to maintain constant voltage across the LT3093, optimizing efficiency and PSRR.

Wide Negative Input & Adjustable Output –1.8V to –20V input, 0V to –19.5V adjustable output with 200mA output current and 190mV typical dropout voltage. H-Grade specified for –40°C to +150°C.

Circuit Considerations for LT3093HDD#TRPBF

Output Voltage & Current Limit Programming

The LT3093HDD#TRPBF offers flexible output and current limit configuration:

Output Voltage (SET Pin): A resistor from SET to GND programs the output voltage. The SET pin sinks a precision 100µA current, so V_OUT = –(100µA × R_SET). Output voltage range is 0V to –19.5V.
Noise & PSRR Improvement: Adding a capacitor from SET to GND improves noise, PSRR, and transient response. Use a low-leakage capacitor to avoid DC errors.
Programmable Current Limit (ILIM Pin): A resistor from ILIM to GND sets the current limit (scale factor nominally 1.95A·kΩ). Kelvin connect this resistor directly to the GND pin for best accuracy.
Fast Start-Up (PGFB Pin): The PGFB pin activates fast start-up circuitry. If fast start-up is not needed, tie PGFB to IN. This allows the use of large SET pin capacitors without long start-up times.
VIOC Tracking (VIOC Pin): The VIOC pin controls an upstream regulator to maintain a constant differential voltage across the LT3093, optimizing efficiency and PSRR. Float if unused.

PCB and System-Level Guidance

Negative LDO regulator performance depends on layout and component selection:

Input Capacitor: A 4.7µF input bypass capacitor from IN to GND generally suffices. Applications with large load transients may require higher input capacitance.
Output Capacitor: Stable with a minimum 4.7µF ceramic output capacitor.
Exposed Pad: The exposed pad (Pin 13) is IN and must be soldered to the PCB. The DFN package has a thermal resistance (θ_JA) of 34°C/W and (θ_JC) of 5.5°C/W.
Kelvin Sense (OUTS Pin): Connect the OUTS pin directly to the output capacitor for optimal transient performance and load regulation.
EN/UV Pin: The EN/UV pin is bidirectional and can be switched with either a positive or negative voltage. Do not float. If unused, tie EN/UV to IN. The turn-on threshold is approximately ±1.26V.
Verify the recommended PCB footprint from the official datasheet prior to production.
