SBVS031C – MARCH 2001 – REVISED MARCH 2003

DMOS

400mA Low-Dropout Regulator

DESCRIPTION

FEATURES

The REG113 is a family of low-noise, low-dropout linear

regulators with low ground pin current. Its new DMOS topol-

ogy provides significant improvement over previous designs,

including low-dropout voltage (only 250mV 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 re-

quire expensive low ESR capacitors greater than 1µF.

● CAP-FREE DMOS TOPOLOGY:

Ultra Low Dropout Voltage:

250mV typ at 400mA

Output Capacitor not Required for Stability

● UP TO 500mA PEAK, TYPICAL

● FAST TRANSIENT RESPONSE

●

VERY LOW NOISE: 28µVrms

● HIGH ACCURACY: ±1.5% max

● HIGH EFFICIENCY:

Typical ground pin current is only 850µA (at I_OUT= 400mA)

and drops to 10nA when not enabled. Unlike regulators with

PNP pass devices, quiescent current remains relatively con-

stant over load variations and under dropout conditions.

I_GND= 850µA at I_OUT= 400mA

Not Enabled: I_GND= 0.01µA

The REG113 has very low output noise (typically 28µVrms

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).

● 2.5V, 2.85V, 3.0V, 3.3V, AND 5.0V OUTPUT VERSIONS

● OTHER OUTPUT VOLTAGES AVAILABLE UPON

REQUEST

● FOLDBACK CURRENT LIMIT

● THERMAL PROTECTION

● SMALL SURFACE-MOUNT PACKAGES:

SOT23-5 and MSOP-8

The REG113 is well protected—internal circuitry provides a

current limit which protects the load from damage, further-

more, thermal protection circuitry keeps the chip from being

damaged by excessive temperature. The REG113 is avail-

able in SOT23-5 and MSOP-8 packages.
