Description
The LD39015Jxx provides 150 mA maximum current from an input voltage ranging from 1.5 V to 5.5 V with a typical dropout voltage of 80 mV. It is stable with ceramic capacitor. The ultra low drop-voltage, low quiescent current and low noise features make it suitable for low power battery powered applications. Power supply rejection is 74 dB at low frequencies and starts to roll off at 10 kHz. Enable logic control function puts the LD39015Jxx in shut-down mode allowing a total current consumption lower than 1 µA. The device also includes a short-circuit constant current limiting and thermal protection. Typical applications are mobile phones, personal digital assistant (PDAs), cordless phone and similar battery powered systems. Flip-chip 4 Table 1. Device summary

Note: Absolute maximum ratings are those values beyond which damage to the device may occur. Functional operation under these conditions is not implied. All values are referred to GND. Table 3. Absolute maximum ratings Table 4. Thermal data
5 Electrical characteristics
Table 5. Electrical characteristics
- Dropout voltage is the input-to-output voltage difference at which the output voltage is 100 mV below its nominal value. This
specification does not apply for output voltages below 1.5 V.
- Turn-on time is time measured bet ween the enable input just exceeding VEN High Value and the output voltage just
reaching 95% of its nominal value. Table 5. Electrical characteristics (continued)
