LDCL015MR STMicroelectronics

LDCL015 150 mA capless ultra low drop linear regulator ICs Datasheet - production data Description The LDCL015 provides 150 mA of maximum current from an input voltage ranging from 1.8 V to 5.5 V, with a typical dropout voltage of 50 mV. It is stable with no input or output capacitor. Low SOT23-5L quiescent current, low noise and capless operation make it suitable for low power battery- powered applications and allows the reduction of board size. Typical power supply rejection ratio is Features 52 dB at low frequencies, and starts to roll off at 10 kHz. The Enable logic control function puts the No input or output capacitor required LDCL015 in shutdown mode, reducing the total Input voltage from 1.8 V to 5.5 V current consumption to less than 1 A. The device also includes short-circuit constant current Very low drop: 50 mV at 100 mA load limit and thermal protection. Typical applications 2% output voltage accuracy are mobile phones, personal digital assistants and Output voltage tolerance over temperature: similar battery-powered systems. 3% Low noise 150 mA guaranteed output current Available in fixed and adjustable output voltages, from 0.8 V in 100 mV steps Internal current and thermal limit Operating temperature range: - 40 C to 125 C SOT23 5-lead package Applications Space-sensitive applications Battery-powered equipment Cordless and mobile phones Industrial and medical equipment Portable equipment Table 1.
