Product Summary

The REG102NA-2.5 is a DMOS 250mA Low-Dropout Regulator. It provides significant improvement over previous designs, including low-dropout voltage (only 150mV typ at full load), and better transient performance. In addition, no output capacitor of the REG102NA-2.5 is required for stability, unlike conventional low-dropout regulators that are difficult to compensate and require expensive low ESR capacitors greater than 1μF. The applications of the REG102NA-2.5 include: (1)portable communication devices; (2)battery-powered equipment; (3)personal digital assistants; (4)modems; (5)bar-code scanners; (6)backup power supplies.

Parametrics

REG102NA-2.5 absolute maximum ratings: (1)Supply Input Voltage, VIN: –0.3V to 12V; (2)Enable Input Voltage, VEN: –0.3V to VIN; (3)Feedback Voltage, VFB: –0.3V to 6.0V; (4)NR Pin Voltage, VNR: –0.3V to 6.0V; (5)Output Short-Circuit Duration: Indefinite; (6)Operating Temperature Range (TJ): –55℃ to +125℃; (7)Storage Temperature Range (TA): –65℃ to +150℃; (8)Lead Temperature (soldering, 3s): +240℃.

Features

REG102NA-2.5 features: (1)new dmos topology: ultra low dropout voltage: 150mv typ at 250ma, output capacitor not required for stability; (2)fast transient response; (3)very low noise: 28μvrms; (4)high accuracy: ±1.5% max; (5)high efficiency: ignd = 600μa at iout = 250ma, not enabled: ignd = 0.01μa; (6)2.5v, 2.8v, 2.85v, 3.0v, 3.3v, and 5.0v adjustable output versions; (7)other output voltages available upon request; (8)foldback current limit; (9)thermal protection; (10)small surface-mount packages: sot23-5, sot223-5, and so-8.
