CAT6217
150 mA CMOS LDO
Regulator
Description
The CAT6217 is a 150 mA CMOS low dropout regulator that
provides fast response time during load current and line voltage
changes.
http://onsemi.com
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 150 ms.
5
1
With zero shutdown current and low ground current of 55 mA
typical, the CAT6217 is ideal for battery−operated devices with supply
voltages from 2.3 V to 5.5 V. An internal under voltage lockout circuit
disables the output at supply voltages under 2.1 V typical.
The CAT6217 offers 1% initial accuracy and low dropout voltage,
90 mV typical at 150 mA. Stable operation is provided with a 1 mF
ceramic capacitor, reducing required board space and component cost.
Other features include output short−circuit current limit and thermal
protection.

IN
operating input voltage range is from 2.3 V to 5.5 V.
EN is the enable control logic (active high) for the regulator
output. It has a 2.5 MW pull−down resistor, which assures
that if EN pin is left open, the circuit is disabled.
GND is the ground reference for the LDO. The pin must be
connected to the ground plane on the PCB.
BYP is the reference bypass pin. An optional 0.01 mF
capacitor can be connected between BYP pin and GND to
reduce the output noise and enhance the PSRR at high
frequency.
VOUT is the LDO regulator output. A small 1 mF ceramic
bypass capacitor is required between the V
pin and

ground for stability. For better transient response, its value
can be increased to 4.7 mF.
