High PSRR, Low-Dropout, 150mA

Linear Regulators

1/MAX892

General Description

Features

The MAX8891/MAX8892 low-dropout (LDO) linear regu-

lators are designed to deliver up to 150mA continuous

output current. These regulators achieve a low 120mV

dropout for 120mA load current.

♦ Space-Saving SC70 Package

♦ 65dB PSRR at 10kHz

♦ 120mV Dropout at 120mA Load

The MAX8891 only requires an input/output capacitor,

hence achieving the smallest PCB area. The

MAX8892’s output voltage can be adjusted with an

external divider.

♦ Stable with 1µF Ceramic Capacitor for Any Load

♦ Guaranteed 150mA Output

♦ Only Need Input and Output Capacitors (MAX8891)

♦ Output Voltages: 1.5V, 1.8V, 2.5V, 2.6V, 2.7V, 2.8V,

2.85V, 3V, 3.3V, 4.5V (MAX8891) and Adjustable

(MAX8892)

The MAX8891 is preset to a variety of voltages in the

1.5V to 4.5V range. Designed with a p-channel

MOSFET series pass transistor, the MAX8891/MAX8892

maintain very low ground current (40µA).

♦ Low 40µA Ground Current

The regulators are designed and optimized to work with

low-value, low-cost ceramic capacitors. The MAX8891/

MAX8892 require only 1µF (typ) of output capacitance

for stability with any load. When disabled, current con-

sumption drops to below 1µA.

♦ Excellent Load/Line Transient

♦ Overcurrent and Thermal Protection

Ordering Information

These regulators are available in a tiny 5-pin SC70

package.
