MCP1702 Introduction

The MCP1702 is aLow Drop Out voltage regulatorfrom Microchip. It is a family of CMOS low dropout (LDO) voltage regulators that is capable of regulating voltage efficiently with alow voltage drop of 625mVand can provide output voltage almost close to the input voltage. The output voltage tolerance of the MCP1702 is typically ±0.4% at +25°C and ±3% maximum over the operating junction temperature range of -40°C to +125°C. Line regulation is ±0.1% typical at +25°C and Load regulation is ±1.0. MCP1702 is generally used inBattery-powered Devices.

How to use the MCP1702

MCP1702 low dropout regulator comes in 3-pin package. It is most commonly used as avoltage regulator. Its low quiescent current and low dropout voltage makes it ideal for many battery-powered applications. Using MCP1702 as a voltage regulator is pretty simple. Connect the Vin pin to the power source and GND pin to ground. The regulated output can be obtained at the Vout pin. Output voltage range for MCP1702 is 1.2V to 5V. 1µf ceramic capacitor is used for LDO output stability.
