Overview

EUP7914 150mA Low-Noise LDO in SC-82 Without A Bypass Capacitor DESCRIPTION The EUP7914 is an efficient CMOS low dropout (LDO) voltage regulator optimized for ultra-low-noise applications.
It offers high output accuracy, extremely low dropout voltage, low ground current and fast start-up time.
The EUP7914 provides a very low noise output without a bypass capacitor, ideal for RF applications where a clean supply voltage source is required.
Specifically designed for handheld and battery-powered devices, the EUP7914 provides a TTL-logic-compatible enable pin.
When the EUP7914 is disabled, power consumption drops nearly to zero.
Key features include current limit, thermal shutdown and faster transient response.
The EUP7914 works with low-ESR ceramic capacitors.
Available in the SC-82 space saving package which reduces the amount of board space for power applications.
The EUP7914 offers wide fixed output voltage versions.
