Overview

Description

The LP2951CM-3.3 is a fixed 3.3V low-dropout regulator (LDO) from the LP2951 family. It provides a regulated 3.3V output from a higher single-supply input with very low quiescent current, making it suitable for battery-powered or micropower electronics.
Key points:
- Fixed output: 3.3V
- Very low quiescent current (micropower operation)
- Output current typically up to ~100 mA
- Low dropout (several hundred millivolts depending on load)
- Protection: short-circuit protection and thermal shutdown
- Input/output capacitors recommended for stability (per datasheet)
Pinout (three pins): Input, Ground, Output (package variant CM). The CM suffix refers to the specific package variant.
Applications:
- Battery-powered microcontroller/embedded projects
- Sensor and portable electronics
- Any single-supply system needing a stable 3.3V rail
Note: For exact electrical specs, recommended capacitor values, and package details, consult the LP2951CM-3.3 datasheet.

Package

TO-92 molded plastic, 3-pin through-hole package.

Pinout

- Pin count: 3 pins
- Function: Fixed 3.3 V low-dropout positive voltage regulator. Pins are Vin (input), GND (ground), and Vout (regulated 3.3 V output). Includes protection features (current limit and thermal shutdown) per the LP2951 family.

Manufacturer

Manufacturer: Texas Instruments (TI). TI is a multinational American semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits.

Application

LP2951CM-3.3 is a fixed 3.3V low-dropout regulator. Applications: power supply for 3.3V digital/mixed-signal logic in battery-powered/portable gear; microcontrollers, DSPs, memories, and ASICs; sensors, RF/transceiver modules; embedded system rails; pre-regulation for analog front-ends; low-quiescent-current rail in portable instrumentation and audio/video gear.
