LD39015M25R
LD39015M25R is 150mA low quiescent current and low noise voltage regulator manufactured by STMicroelectronics.
- Part of the LD39015 comparator family.
- Part of the LD39015 comparator family.
Description
SOT23-5L
Features
- Input voltage from 1.5 to 5.5 V
- Ultra low-dropout voltage (80 m V typ. at 100 m A load)
- Very low quiescent current (18 µA typ. at no load, 38 µA typ. at 150 m A load, 1 µA max. in OFF mode)
- Very low noise without bypass capacitor (29 µVRMS at VOUT = 0.8 V)
- Output voltage tolerance: ± 2.0% @ 25 °C
The LD39015 series provides 150 m A maximum current with an input voltage range from 1.5 V to 5.5 V and a typical dropout voltage of 80 m V. It is stable with ceramic capacitors. The ultra low drop voltage, low quiescent current and low noise features make it suitable for low power batterypowered applications. Power supply rejection is 65 d B at low frequencies and starts rolling off at 10 k Hz. Enable logic control function puts the LD39015 in shutdown mode allowing a total current consumption lower than 1 µA. The device also includes short-circuit constant current limiting and thermal protection. Typical applications are mobile phones, personal digital assistants (PDAs), cordless phones or similar batterypowered systems.
- 150 m A guaranteed output current
- Wide range of output voltages available on request: 0.8 V to 3.3 V with 100 m V step
- Logic-controlled electronic shutdown
