- Ventron No:
- 3767419-LD3985G27R
- Description:
- IC REG LDO 2.7V 0.15A TSOT23-5
- Datasheet:
- LD3985G27R
Description
The LD3985 is a low-dropout, low-noise voltage regulator that provides up to 150 mA of current from an input voltage range of 2.5 V to 6 V. It is designed to work with low ESR ceramic capacitors and features an ultra-low dropout voltage (60 mV typ. at 150 mA load, 0.4 mV typ. at 1 mA load), very low quiescent current (85 μA typ. at no load, 170 μA typ. at 150 mA load; max. 1.5 μA in OFF mode), and a wide range of output voltage options (1.22 V, 1.8 V, 2.5 V, 2.6 V, 2.7 V, 2.8 V, 2.9 V, 3 V, 3.3 V, 4.7 V). The LD3985 also has a fast turn-on time (typ. 200 μs [Co 1 μF, CBYP 10 nF and lo 1 mA]), logic-controlled electronic shutdown, internal current and thermal limit, and output low noise voltage (30 μVRMS over 10 Hz to 100 kHz). It operates over a temperature range of -40 °C to 125 °C.
