Description
The DIA7965 series is a 500 mA, ultra-high Power
Supply Ripple Rejection (PSRR) low dropout CMOS
linear regulator. The device features ultra-high PSRR
and low noise to meet the requirements of RF and
other sensitive analog circuits in automotive
applications.
The DIA7965 operates an input voltage range of 1.65
V to 5.5 V and supports fixed output voltage from 1 V
to 3.3 V. With 18 µA low quiescent current at no load,
the DIA7965 is quite suitable for systems requiring
low power and provides fast line and load transient
performance.
The DIA7965 is stable with an 1 µF input and an 1 µF
output small ceramic capacitor, allowing for a small
overall solution size. A precision band-gap and error
amplifier provide high accuracy of ±2% over
operating temperature range. The DIA7965 is
available in SOT23-5 and tiny DFN1*1-4 packages.
