LD59015 150 mA low noise and high PSRR linear voltage regulator Datasheet - production data * Package: SOT323-5L * Temperature range: -40 C to 125 C Description SOT323-5L Features * Input voltage from 2.4 to 5.5 V * Very low quiescent current (31 A typ. at no load, 75 A typ. at 150 mA load, 1 A max. in OFF mode) * Very low noise (20 VRMS at VOUT = 1.5 V) * Output voltage tolerance: 1.8% at 25 C * 150 mA guaranteed output current The LD59015 provides 150 mA maximum current with an input voltage range from 2.4 V to 5.5 V, and a typical dropout voltage of 150 mV. It is stable with ceramic capacitors. High PSRR, low quiescent current and low noise features make it suitable for low power battery-powered applications. Power supply rejection is 80 dB at low frequency and starts to roll off at 10 kHz. The enable logic control function puts the LD59015 in shutdown mode, allowing a total current consumption lower than 1 A. The device also includes short-circuit constant current limiting and thermal protection. Typical applications are mobile phones, personal digital assistants (PDAs), cordless phones and similar batterypowered systems. * Wide range of output voltages available on request: 0.8 V to 3.3 V in 100 mV steps * Logic-controlled electronic shutdown * Compatible with ceramic capacitors * Very high PSRR (80 dB @ 100 Hz, 76 @ 10 kHz, 54 @ 100 kHz) * Internal current and thermal limit Table 1.
