PRODUCT OVERVIEW

What Is the LT3090HMSE#TRPBF?

LT3090HMSE#TRPBF is a 600mA, low dropout negative linear regulator from Analog Devices that is easily parallelable to increase output current or spread heat on surface mounted boards. Designed with a precision current reference followed by a high performance rail-to-rail voltage buffer, this regulator finds use in applications requiring precision output, high current with no heat sink, output adjustability to zero, and low dropout voltage.[reference:0]

The LT3090 features fast transient response, high PSRR, and output noise as low as 18µVRMS. The device generates a wide output voltage range (0V to –32V) while maintaining unity gain operation, yielding virtually constant bandwidth, load regulation, PSRR, and noise regardless of the programmed output voltage.[reference:1]

The LT3090 supplies 600mA at a typical dropout voltage of 300mV. Operating quiescent current is nominally 1mA and drops to less than 1µA in shutdown. A single resistor adjusts the LT3090's precision programmable current limit. The LT3090's positive or negative current monitor either sources a current (0.5mA/A) or sinks a current (1mA/A) proportional to output current. Built-in protection includes reverse output protection, internal current limit with foldback, and thermal shutdown with hysteresis.[reference:2]

The LT3090HMSE#TRPBF is the H-Grade version in a thermally enhanced 12-lead MSOP package with an exposed pad, rated for operation from –40°C to +150°C. The device is RoHS compliant, REACH unaffected, and in active production.

600mA Output Current Low dropout negative linear regulator with 300mV typical dropout voltage at full load.

Wide –1.5V to –36V Input Range Rail-to-rail output voltage range from 0V to –32V with unity gain operation for constant bandwidth, PSRR, and noise.

18µVRMS Low Output Noise Single-resistor output voltage setting, programmable current limit, and parallelable for higher current and heat spreading.

Circuit Considerations for LT3090HMSE#TRPBF

Output Voltage & Current Limit Programming

The LT3090HMSE#TRPBF offers flexible output configuration:

Output Voltage Setting: A single resistor between the SET pin and GND programs the output voltage from 0V to –32V. The SET pin sources a precision 50µA current with ±1% initial accuracy.
Programmable Current Limit: An external resistor on the ILIM pin sets the precision current limit, allowing optimization for different load requirements.
Parallel Operation: Multiple LT3090 devices can be paralleled to increase output current or spread heat on surface mounted boards.
Current Monitor: The output current monitor sources (0.5mA/A) or sinks (1mA/A) a current proportional to output current, enabling system-level monitoring.
3-Terminal Floating Regulator: The device can be configured as a 3-terminal floating regulator for additional application flexibility.

PCB and System-Level Guidance

Negative LDO regulator performance depends on layout and component selection:

Input Capacitor: Place a minimum 4.7µF low-ESR capacitor close to the IN pins for stable operation. Ceramic or tantalum capacitors are both acceptable.
Output Capacitor: Stable with a minimum 4.7µF ceramic or tantalum output capacitor.
SET Pin Resistor: Keep the SET pin resistor trace short and close to the device for accurate voltage setting.
Exposed Pad: The exposed thermal pad on the MSOP package must be soldered to the PCB ground plane for optimal thermal performance.
Positive Supply: The exposed pad must be connected to a positive supply voltage (at least 3V) for proper operation.
Verify the recommended PCB footprint from the official datasheet prior to production.
