Microchip 5V Fixed LDO Voltage Regulator SOT-23-3

Microchip 5V Fixed LDO Voltage Regulator provides a stable 5V fixed output in a compact SOT-23-3 surface-mount package, making it suitable for power-sensitive and battery-operated designs.

Overview

This CMOS low-dropout (LDO) linear regulator delivers a fixed 5V output with a typical tolerance of ±0.4%. It has a dropout voltage of 178mV at the full 250mA output current, which helps minimise power loss as battery voltage declines. Its typical quiescent current of 1.6µA suits always-on and standby operation, where conserving battery charge is important. The regulator is stable with a small 1.0µF ceramic output capacitor, which simplifies board design and saves space.

Key Features

• Extended battery life through low dropout voltage
• Fixed 5V output with typical tolerance of ±0.4%
• Output current up to 250mA in a SOT-23-3 surface-mount package
• Short-circuit and over-temperature protection
• Typical quiescent current of 1.6µA for low power operation
• Stable with a 1.0µF ceramic output capacitor
• Maximum input voltage of 6V

Applications

The regulator is designed for portable and battery-operated devices, power-sensitive circuits, and space-constrained designs. It can also serve as a direct, pin-compatible upgrade for older bipolar regulators such as the TC55.
