EUP7982

300mA Low-Noise Ultra Low-Dropout

CMOS Regulator with Fault Indicator

FEATURE

DESCRIPTION

2.5V to 5.5V Input Range

The EUP7982 low-noise, low-dropout, linear

regulator operates from a 2.5V to 5.5V input and is

guaranteed to deliver 300mA.

300mA Guaranteed Output Current

60dB PSRR at 1kHz

50µV RMS Output Voltage Noise (10Hz to

100kHz)

The EUP7982 is stable with small 2.2µF ceramic

capacitor. Its performance suits battery powered

applications because of its shutdown mode (60 nA

typ), low quiescent current (110µA typ), and LDO

voltage (140mV typ). The low dropout voltage

allows for more utilization of a battery’s available

energy by operating closer to its end-of-life voltage.

An output fault-detection circuit indicates loss of

regulation.

140mV Dropout at 300mA

Low 110µA No-Load Supply Current

≤1µA Shutdown Current

Fast Start-up Time

Stable With 2.2µF Ceramic Output Capacitors

Thermal Shutdown and Short-Circuit Protection

Fault Indicator

RoHS Compliant and 100% Lead (Pb)-Free

The EUP7982 is available in MSOP package with

1.8V, 2.5v, 2.8V, 3V, 3.3V, and adjustable versions.

APPLICATIONS

Wireless Handsets

DSP Core Power

Battery Powered Electronics

Portable Information Appliances
