Features & Applications
The LD1117AS12TR is a low drop fixed positive voltage regulator with an output voltage of 1.2 V and an output current up to 1 A. It is available in surface mount SOT-223-3 package.
High efficiency is assured by an NPN pass transistor. Only a very common 10 μF minimum capacitor is needed for stability. Chip trimming allows the regulator to reach a very tight output voltage tolerance, within ±2% at 25 °C.
Features:
- Low dropout voltage:
- 1.15 V typ. @ IOUT= 1 A, 25 °C
- Very low quiescent current:
- 5 mA typ. @ 25 °C
- Output current up to 1 A
- Fixed output voltage of:
- 1.2 V, 1.8 V, 2.5 V, 3.3 V
- Adjustable version availability (VREF= 1.25 V)
- Internal current and thermal limit
- Only 10 μF for stability
- Available in ±2% (at 25 °C) and 4% in full temperature range
- High supply voltage rejection:
- 80 dB typ. (at 25 °C)
- Temperature range: 0 °C to 125 °C
