STMicroelectronics LDFM
The LDFM is a fast, very low drop linear regulator which operates from an input supply voltage in the range of 2.5 V to 16 V. It is available in fixed and adjustable output voltage versions, from 0.8 V to 12 V. The LDFM features high output precision, very low dropout voltage, low noise, and low quiescent current, therefore suitable for low voltage microprocessors and memory applications.| Part No. | LDFM |
