11 / 29 page VIN VOUT ON/OFF Overcurrent/ Overtemperature Protection VREF 1.23 V − + BYPASS LP2985 www.ti.com SLVS522O – JULY 2004 – REVISED JANUARY 2015 7 Detailed Description 7.1 Overview The LP2985 family of fixed-output, low-dropout regulators offers exceptional, cost-effective performance for both portable and nonportable applications. Available in voltages of 1.8 V, 2.5 V, 2.8 V, 2.9 V, 3 V, 3.1 V, 3.3 V, 5 V, and 10 V, the family has an output tolerance of 1% for the A version (1.5% for the non-A version) and is capable of delivering 150-mA continuous load current. Standard regulator features, such as overcurrent and overtemperature protection, are included. 7.2 Functional Block Diagram 7.3 Feature Description The LP2985 has a host of features that makes the regulator an ideal candidate for a variety of portable applications: • Low dropout: A PNP pass element allows a typical dropout of 280 mV at 150-mA load current and 7 mV at 1- mA load. • Low quiescent current: The use of a vertical PNP process allows for quiescent currents that are considerably lower than those associated with traditional lateral PNP regulators. • Shutdown: A shutdown feature is available, allowing the regulator to consume only 0.01 μA when the ON/OFF pin is pulled low. • Low-ESR-capacitor friendly: The regulator is stable with low-ESR capacitors, allowing the use of small, inexpensive, ceramic capacitors in cost-sensitive applications. • Low noise: A BYPASS pin allows for low-noise operation, with a typical output noise of 30 μVRMS, with the use of a 10-nF bypass capacitor. • Small packaging: For the most space-constrained needs, the regulator is available in the SOT-23 package. 7.4 Device Functional Modes 7.4.1 Normal Operation In normal operation, the device will output a fixed voltage corresponding with the orderable part number. The device can deliver 150 mA of continuous load current. 7.4.2 Shutdown Mode Set the ON/OFF pin low to shut down the device when VIN is still present. If a shutdown mode is not needed, tie the pin to VIN. For proper operation, do not leave ON/OFF unconnected, and apply a signal with a slew rate of ≥40 mV/μs.
