DESCRIPTION
The CAT6217 is a 150mA CMOS low dropout regulator that provides fast response time during load current and line voltage changes.
The quick-start feature allows the use of an external bypass capacitor to reduce the overall output noise without affecting the turn-on time of just 150μs.
With zero shutdown current and low ground current of 55μA typical, the CAT6217 is ideal for battery operated devices with supply voltages from 2.3V to 5.5V. An internal under voltage lockout circuit disables the output at supply voltages under 2.1V typical.
The CAT6217 offers 1% initial accuracy and low dropout voltage, 90mV typical at 150mA. Stable operation is provided with a 1μF ceramic capacitor, reducing required board space and component cost.
Other features include output short-circuit current limit and thermal protection.
The device is available in the low profile (1mm max height) 5-lead TSOT-23 package.
