Descripción general

Description

LP5912-3.3DRVT is Texas Instruments’ fixed-output low-dropout regulator (LDO) that provides a regulated 3.3 V rail. It’s intended for microcontrollers, sensors, and other circuitry that need a stable 3.3 V supply from a higher input.
Key points
- Fixed output: 3.3 V
- Low-dropout, suitable for battery-powered or low-voltage designs
- Built-in protections: short-circuit/overcurrent and thermal shutdown
- Stable with recommended output capacitors (per datasheet)
- Package: DRVT (compact surface-mount)
How to use (high level)
- VIN -> input supply, GND -> ground, VOUT -> load rail
- Add the recommended output capacitor close to VOUT for stability
- Ensure input voltage and operating temperature stay within datasheet ratings
For exact electrical specs (input range, dropout, quiescent current, capacities, and pinout), consult the TI LP5912-3.3DRVT datasheet.

Features

Concise features of LP5912-3.3DRVT (3.3 V fixed LDO):
- Fixed 3.3 V output
- Output current: up to ~150 mA
- Low dropout voltage (typical ~0.2–0.3 V at moderate load)
- Very low quiescent current
- Low noise with good PSRR
- Stable with ceramic output capacitors (min ~2.2 µF, low ESR)
- Protection: thermal shutdown and current/short-circuit protection
- RoHS-compliant; available in DRVT package
- Suitable for battery-powered/compact systems requiring a stable 3.3 V rail

Package

SOT-23-5 (5-pin SOT-23) package.

Pinout

8 pins (8-pin package, e.g., SOIC/TSSOP-8). Function: fixed 3.3 V low-dropout regulator (LDO) that accepts input voltage and outputs 3.3 V; typical pins include VIN, VOUT, GND, and EN (enable), with remaining pins as no-connect depending on package variant.

Manufacturer

Manufacturer: Texas Instruments (TI).
What kind of company: TI is a global American semiconductor company that designs, manufactures, and sells analog and embedded processing integrated circuits, sensors, microcontrollers, and related products for various industries.

Application
