Product Overview
LD1117ADT12TR is a low-drop voltage regulator able to provide up to 1A of output current. High efficiency is assured by an NPN pass transistor. Only a very common 10µF minimum capacitor is needed for stability. Chip trimming allows the regulator to reach a very tight output voltage tolerance, within ±2% at 25°C.
- Low dropout voltage: 1.15V typical at IOUT = 1A, 25°C
- Very low quiescent current: 5mA typical at 25°C
- Internal current and thermal limit
- Only 10µF for stability
- Operating input voltage is 10V max ( IO = 100mA)
- Output noise voltage is 100µV typ (B = 10Hz to 10KHz, TJ = 25°C)
- Supply voltage rejection is 80dB typ (IO = 40mA, f = 120Hz, VI - VO = 3V, Vripple = 1VPP)
- Thermal regulation is 0.08%/W typ ( Ta = 25°C, 30ms pulse)
- 1.2V output voltage
- DPAK package, 0°C to 125°C temperature range
