Micropower, 500mA Low Noise CMOS LDO Regulator

Features

Product Description

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.

• 500mA output current capability

• 500mA peak in SOT-23 package

• 500mA continuous in MSOP package

• 500mV maximum dropout voltage at full load

• Excellent line and load regulation

• Stable with any output capacitor

• Ultra low noise with optional bypass capacitor

• Fast power-up with bypass capacitor

• “Zero” current in Shutdown mode

• Thermal Overload Protection

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.

• Foldback Current Limiting Protection

• Reverse current protection

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.

Applications

•

Notebook, and palmtop computers

Cell phones and battery powered devices

Consumer and personal electronics

PC Card Vcc and Vpp regulation and switching

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.

Table 1: CM3019 Regulator Family

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.

For other output voltages, please contact the factory

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

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

applications.
