Product Summary
The REG113NA-3 is a low-noise, low-dropout linear regulator with low ground pin current. New DMOS topology of REG113NA-3 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 lowdropout regulators that are difficult to compensate and require expensive low ESR capacitors greater than 1μF.
Parametrics
REG113NA-3 absolute maximum ratings: (1)Supply Input Voltage, VIN: –0.3V to 12V; (2)Enable Input Voltage, VEN: –0.3V to VIN; (3)NR Pin Voltage, VNR: -0.3V to 6.0V; (4)Output Short-Circuit Duration: Indefinite; (5)Operating Temperature Range (TJ): –55℃ to +125℃; (6)Storage Temperature Range (TA): –65℃ to +150℃; (7)Lead Temperature (soldering, 3s): +240℃.
