The CM3019 is a CMOS linear voltage regulator with low

quiescent current, very low drop out voltage and better

than 1% initial output voltage accuracy.

The quiescent current is typically 150µA at light loads and

only 165µA at 500mA. This is 5% more efficient than

equivalent Bi-CMOS devices that can waste up to 25mA at

500mA.

Load regulation is maintained for peak currents up to

500mA. This is useful for supplying inrush currents during

power-up and transient conditions. Continuous output

current is limited by package type and board layout.

A dedicated control input (EN, Active High) has been

included for power-up sequencing flexibility. When this

input is taken low, the regulator is disabled. In this state,

the supply current will drop to near zero.

The device also features reverse current protection. This

protects the device by blocking the pass transistors

parasitic diode when the output voltage is forced higher

than the input.

For low noise performance and increased power supply

ripple rejection a noise bypass capacitor can be connected

to the BYP pin. Connecting this capacitor will not

significantly delay the speed of power-up.

The CM3019 is fully protected, offering both overload

current limiting and high temperature thermal shutdown.

To reduce board cost and layout size the CM3019 was

designed to be stable with or without any output capacitor.

This includes tiny, low ESR ceramic capacitors.

Housed in a low profile MSOP8 package, or a SOT23-

5/SOT23-6, the device is ideal for space critical

applications.
