1 LD ma low quiescent current and low noise voltage regulator Datasheet - production data Compatible with ceramic capacitors C O = 1 µf Internal current and thermal limit Temperature range: -40 C to 125 C Description SOT23-5L The LD39015 series provides 150 ma maximum current with an input voltage range from 1.5 V to 5.5 V and a typical dropout voltage of 80 mv. It is stable with ceramic capacitors. The ultra low drop Features voltage, low quiescent current and low noise features make it suitable for low power batterypowered applications. Power supply rejection is Input voltage from 1.5 to 5.5 V Ultra low-dropout voltage (80 mv typ. at db at low frequencies and starts rolling off at ma load) 10 khz. Enable logic control function puts the LD39015 in shutdown mode allowing a total Very low quiescent current (18 µa typ. at no current consumption lower than 1 µa. The device load, 38 µa typ. at 150 ma load, 1 µa max. in also includes short-circuit constant current limiting OFF mode) and thermal protection. Typical applications are Very low noise without bypass capacitor mobile phones, personal digital assistants (29 µv RMS at V OUT = 0.8 V) (PDAs), cordless phones or similar batterypowered systems. Output voltage tolerance: ± 25 C 150 ma guaranteed output current Wide range of output voltages available on request: 0.8 V to 3.3 V with 100 mv step Logic-controlled electronic shutdown Table 1.
