40V 150mA Low IQ Fixed Output Voltage (3.3V, 3.6V, 5V, 9V) Low Dropout Regulators

The RAA21440x family, RAA214403 (3.3V),

RAA214404 (3.6V), RAA214405 (5V), and

RAA214409 (9V) are low-quiescent current fixed

output voltage low-dropout regulators capable of

sourcing up to 150mA to a load. The LDO has a wide

input voltage range up to 40V.

Features

▪ Typical low-quiescent current: 3.8µA at no load

▪ Typical shutdown current (SOT23 package):

<0.5µA

▪ Wide input voltage range: up to 40V with 45V line

transient tolerance

The LDOs feature a ±3% output voltage accuracy

(over line, load, and temperature), input UVLO with

hysteresis, enable control, internal current limit, and

over-temperature shutdown protection.

▪ Max output current: 150mA

▪ Output voltage accuracy: ±3% over line, load, and

temperature

▪ Typical dropout voltage: 0.5V at 100mA

The LDOs are stable with a minimum 2.2µF ceramic

output capacitor. The 3.3V and 5V LDOs are available

in the 5 Ld SOT-23 and the 3 Ld SOT-89 packages.

The 3.6V LDO is available in the 5-Ld SOT-23

package. The 9V LDO is available in the 3 Ld SOT-89

package.

▪ Fixed output voltage options: 3.3V, 3.6V, 5V, and

▪ Stable with 2.2µF minimum ceramic output

capacitor

▪ Overcurrent and over-temperature protection

▪ Junction temperature range: -40°C to 125°C

The combination of low-quiescent current,

low-shutdown current (shutdown function available

with the SOT23 package), and small package size

makes this family of LDOs an ideal choice for portable

devices and battery powered equipment.

Applications

▪ Portable and battery-powered equipment

▪ Notebook computers

▪ Motor drives
