PRODUCT OVERVIEW

What Is the LT3010MPMS8E-5#TRPBF?

LT3010MPMS8E-5#TRPBF is a high-voltage, micropower, low-dropout linear regulator from Analog Devices. The device is capable of supplying 50mA of output current with a dropout voltage of only 300mV, operating over an input voltage range of 3V to 80V[reference:0].

Designed for use in battery-powered or high-voltage systems, the LT3010 features an ultra-low quiescent current of 30µA in normal operation and just 1µA in shutdown, making it an ideal choice for always-on and power-sensitive applications[reference:1]. The regulator is stable with only a 1µF output capacitor and requires no additional ESR for stability, unlike many older regulators that require 10µF to 100µF[reference:2].

The LT3010-5 is the fixed 5V output version of the family. Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting, and reverse current protection[reference:3]. The device is offered in a thermally enhanced 8-lead MSOP package with an exposed pad, which significantly improves heat transfer from the die to the circuit board[reference:4].

The LT3010MPMS8E-5#TRPBF is the MP-grade version, tested and guaranteed over the full –55°C to +125°C operating junction temperature range. The device is AEC-Q100 qualified for automotive applications, RoHS compliant, and in active production.

Wide 3V to 80V Input Range Fixed 5V output with 50mA output current capability, suitable for high-voltage and battery-powered systems.

Ultra-Low Quiescent Current 30µA operating and 1µA in shutdown, with quiescent current well controlled in dropout.

Thermally Enhanced MSOP Package 8-lead MSOP with exposed pad, reducing junction-to-ambient thermal resistance to 30°C/W–40°C/W on a typical board.

Circuit Considerations for LT3010MPMS8E-5#TRPBF

Kelvin Sense & Thermal Design

The LT3010MPMS8E-5#TRPBF offers precision regulation and requires careful thermal design:

SENSE Pin (Pin 2): The SENSE pin is the input to the error amplifier for the fixed 5V output. For optimum regulation, connect SENSE directly to the OUT pin at the load point (Kelvin sense connection) to eliminate the voltage drop across PCB trace resistance[reference:6].
SENSE Pin Bias Current: The SENSE pin bias current is 10µA at the nominal rated output voltage. This bias current flows through the external connection to OUT and should be accounted for in precision applications[reference:7].
Thermal Management: The exposed pad (Pin 9) is electrically connected to GND and must be soldered directly to Pin 4 and the PCB ground plane. Junction-to-case thermal resistance (θ_JC) is 16°C/W, and junction-to-ambient thermal resistance (θ_JA) depends on copper area (40°C/W with 2500mm², 62°C/W with 1000mm²).
Maximum Junction Temperature: For the LT3010MP grade, the maximum rated junction temperature is 125°C. Power dissipation must be calculated to ensure T_J does not exceed this limit under all operating conditions.
Shutdown (SHDN Pin): The SHDN pin puts the device into a low-power shutdown state. The output is off when SHDN is pulled low (<0.3V). It can be driven by 5V logic or open-collector logic with a pull-up resistor. If unused, tie SHDN to a logic high or V_IN[reference:10].

PCB and System-Level Guidance

Linear regulator performance depends on layout and component selection:

Input Capacitor: Place a low-ESR bypass capacitor close to the IN pin. The device is stable with ceramic, aluminum, or tantalum output capacitors.
Output Capacitor: A minimum 1µF output capacitor is required for stability. Larger capacitors may be used for applications with large transient loads to limit peak voltage transients.
Exposed Pad Connection: The exposed backside of the package (Pin 9) is an electrical connection for GND. To ensure optimum device operation, Pin 9 must be connected directly to Pin 4 on the PC board[reference:11].
No Protection Diodes Needed: The device includes internal protection circuitry, eliminating the need for external protection diodes in most applications.
Verify the recommended PCB footprint from the official datasheet prior to production.
