L88R05D集成電路（IC）的線性+開關穩(wěn)壓器規(guī)格書PDF中文資料

Overview

The L88R05 Series is a series of low-saturation voltage regulator ICs that are equipped with a function that generates a reset signal when the power supply for a microcontroller system is turned on or off.

Features

? Minimum I/O voltage difference is small (0.5 V typ.),

making power conservation possible, and makes smaller heatsink and

transformers possible.

? External capacitor for reset signal output delay time adjustment.

? Sink/source reset output provides compatibility with logic circuitry

that has an internal pull-down resistor. Active pull-up

facilitates noise suppression.

? Various types of protective circuits on chip

(fold back current limiting, thermal protection).

? The package is the TO220-5H; this package facilitates designs

for the radiation of heat during the mounting process.

Applications

? Prevents malfunction when the microcontroller power supply

is turned on or off.

? Designed to handle malfunction caused by momentary power

interruptions.

? Suited for portable electronic equipment, mobile electronic

equipment, and other battery-powered equipment with little

capacity to handle fluctuation in input voltage; also suited

for equipment with large fluctuations in the primary power

supply.
