REG101

SBVS026D – JULY 2001 – REVISED SEPTEMBER 2005

DMOS

100mA Low-Dropout Regulator

DESCRIPTION

FEATURES

The REG101 is a family of low-noise, low-dropout linear

regulators with low ground pin current. Its new DMOS

topology provides significant improvement over previous

designs, including low dropout voltage (only 60mV typ at

full load), and better transient performance. In addition, no

output capacitor is required for stability, unlike conventional

low-dropout regulators that are difficult to compensate and

require expensive low ESR capacitors greater than 1µF.

● NEW DMOS TOPOLOGY:

Ultra Low Dropout Voltage:

60mV typ at 100mA

Output capacitor NOT required for stability

● FAST TRANSIENT RESPONSE

●

VERY LOW NOISE: 23µVrms

● HIGH ACCURACY: ±1.5% max

● HIGH EFFICIENCY:

Typical ground pin current is only 500µA (at I_OUT= 100mA)

and drops to 10nA when not in enabled mode. Unlike regula-

tors with PNP pass devices, quiescent current remains rela-

tively constant over load variation and under dropout condi-

tions.

I_GND= 500µA at I_OUT= 100mA

Not Enabled: I_GND= 10nA

● 2.5V, 2.8V, 2.85V, 3.0V, 3.3V, 5.0V, AND

The REG101 has very low output noise (typically 23µVrms

for V_OUT= 3.3V with C_NR= 0.01µF), making it ideal for use

in portable communications equipment. Accuracy is main-

tained over temperature, line, and load variations. Key

parameters are tested over the specified temperature range

(–40°C to +85°C).

ADJUSTABLE OUTPUT VERSIONS

● OTHER OUTPUT VOLTAGES AVAILABLE

UPON REQUEST

● FOLDBACK CURRENT LIMIT

● THERMAL PROTECTION

The REG101 is well protected—internal circuitry provides a

current limit that protects the load from damage. Thermal

protection circuitry keeps the chip from being damaged by

excessive temperature. The REG101 is available in the

SOT23-5 and the SO-8 packages.

● SMALL SURFACE-MOUNT PACKAGES:

SOT23-5 and SO-8

APPLICATIONS

● PORTABLE COMMUNICATION DEVICES

● BATTERY-POWERED EQUIPMENT

● PERSONAL DIGITAL ASSISTANTS

● MODEMS

● BAR-CODE SCANNERS

● BACKUP POWER SUPPLIES
