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 topology 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 re-

quired 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: 33µVrms

● 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 constant 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

33µVrms 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 maintained over tem-

perature, line, and load variations. Key parameters are

guaranteed 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

● BAR-CODE SCANNERS

● BACKUP POWER SUPPLIES

The REG104 is well protected—internal circuitry pro-

vides 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 and the SOT223-5.
