ZXCL SERIES

Micropower SC70-5 & SOT23-5 low dropout regulators

ZXCL5213V25, ZXCL5213V26, ZXCL5213V28, ZXCL5213V30, ZXCL5213V33,

ZXCL250, ZXCL260, ZXCL280, ZXCL300, ZXCL330

Description

The ZXCL series have been designed with space

sensitive systems in mind. They are available in

the ultra small SC70-5 package, which is half the

size of SOT23 based regulators.

The devices can be used with all types of output

capacitors including low ESR ceramics and

typical dropout voltage, is only 85mV at 50mA

load. Supply current is minimised with a ground

pin current of only 50 A at full 150mA load.

Logic control allows the devices to be shut

down, consuming typically less than 10nA.

These features make the device ideal for battery

powered applications where power economy is

critical.

For

applications

requiring

improved

performance over alternative devices, the

ZXCL is also offered in the 5 pin SOT23

package with an industry standard pinout.

The devices feature thermal overload and

over-current protection and are available with

output voltages of 2.5V, 2.6V, 2.8V, 3V, 3.3V.
