DMOS

1A Low-Dropout Regulator

DESCRIPTION

FEATURES

The REG104 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 230mV 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:

230mV typ at 1A and 3.3V Output

Output Capacitor NOT Required for Stability

● FAST TRANSIENT RESPONSE

● VERY LOW NOISE: 33µV_RMS

● HIGH ACCURACY: ±2% max

● HIGH EFFICIENCY:

Typical ground pin current is only 1.7mA (at I_OUT= 1A) and

drops to 0.5µA in not enabled mode. Unlike regulators with

PNP pass devices, quiescent current remains relatively con-

stant over load variations and under dropout conditions.

I_GND= 1.7mA at I_OUT= 1A

Not Enabled: I_GND= 0.5µA

● 2.5V, 2.7V, 3.0V, 3.3V, 5.0V AND

ADJUSTABLE OUTPUT VERSIONS

The REG104 has very low output noise (typically 33µV_RMS

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

in portable communications equipment. On-chip trimming

results in high output voltage accuracy. Accuracy is main-

tained over temperature, line, and load variations. Key pa-

rameters are tested over the specified temperature range

(–40°C to +85°C).

● THERMAL PROTECTION

● SMALL SURFACE-MOUNT PACKAGES:

SOT223-5, DDPAK-5

APPLICATIONS

● PORTABLE COMMUNICATION DEVICES

● BATTERY-POWERED EQUIPMENT

● MODEMS

The REG104 is well protected—internal circuitry provides a

current limit which protects the load from damage. Thermal

protection circuitry keeps the chip from being damaged by

excessive temperature. The REG104 is available in the

DDPAK-5 and the SOT223-5.

● BAR-CODE SCANNERS

● BACKUP POWER SUPPLIES
