Overview

The MIC5365-1.8YC5-TR is a high-performance 150mA low-dropout (LDO) linear regulator designed for portable and space-constrained electronics. It provides a fixed 1.8V output from an input range of 2.5V to 5.5V, offering high PSRR and low quiescent current to maximize battery life.

Why Choose This Part

The regulator features a very small SC-70-5 package and requires only a tiny ceramic output capacitor, reducing total PCB area. It maintains a low quiescent current of 29uA and includes integrated thermal shutdown and current limit protection for improved system robustness.

Applications

Mobile Handsets
Provides a stable 1.8V digital supply rail for baseband processors or memory modules in mobile devices.
Camera Modules
Utilizes its high PSRR to provide clean power to sensitive image sensors and ISP components.
IoT Sensor Nodes
Ideal for battery-powered wireless sensors requiring low standby current and an enable pin for power cycling.
Portable Media Players
Small SC-70 footprint and thermal protection make it suitable for densely packed consumer electronics.

Getting Started

To implement this LDO, place a 1uF ceramic capacitor close to the output pin for stability and a similar capacitor at the input pin. Ensure the Enable (EN) pin is driven high to activate the device or tied to VIN if hardware control is not required.
