Datasheet AS13985 Micropower 150mA Low-Noise LDO 1 General Description The AS13985 is a high-performance low-dropout 150mA voltage regulator designed for use with very-low ESR output capacitors. The device can deliver superior performance in all specifications critical to battery-powered designs, and is perfectly suited for mobile phones, PDAs, MP3 players, and other battery powered devices. Stability is guaranteed with a ceramic output capacitor from 1 to 22µF. The low equivalent series resistance of these capacitors ensures low output impedance at high frequencies. Automatic sleep mode requires less than 1µA quiescent current when pin EN is pulled low. Regulation performance is excellent even under low dropout conditions, when the power transistor has to operate in linear mode. A 10nF bypass capacitor can be added to reduce output noise to 30µV. The low-noise performance allows direct connection of noise sensitive circuits without additional filtering networks. Multiple output voltage options are available as standard products. Contact austriamicrosystems AG for details. The AS13985 is available in a 5-bump WLP package and a 5-pin SOT23 package. 2 Key Features ! Ultra-Low Dropout Voltage (typically 45mV @ 150mA, 0.3mV @ 1mA) Supply Range: 2.5V to 5.5V Output Voltage Range: 1.2V to 5.0V (in 25mV Steps) Output Current: 150mA (Guaranteed) Stable with Low-ESR Output Capacitor Integrated Over-Temperature/Over-Current Protection Low GND Pin Current (only 95µA) Output Voltage Accuracy: 1% Minimal External Components Required High Peak-Current Capability Low Shutdown Current: ≤1µA Operating Temperature Junction Range: -40 to +125°C Smallest Available Packages: - 5-bump WLP - 5-pin SOT23 ! ! ! ! ! ! ! ! ! ! ! ! 3 Applications The AS13985 is ideal for powering cordless and mobile phones, MP3 players, CD and DVD players, PDAs, handheld computers, digital cameras, and any other hand-held battery-powered device.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in Section 6 Electrical Characteristics on page 4 is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Table 2.

The lead finish for Pb-free leaded packages is matte tin (100% Sn). Operating Junction Temperature Storage Temperature Range Package Body Temperature +260 ºC 1. The output PNP structure contains a diode between pins VIN and VOUT that is normally reverse-biased. reversing the polarity of pins VIN and VOUT will activate this diode. 2. The maximum allowable power dissipation is a function of the maximum junction temperature (TJ(MAX), the junction-to-ambient thermal resistance (ΘJA), and the ambient temperature (TAMB). The maximum allowable power dissipation at any ambient temperature is calculated as: P(MAX) = (TJ(MAX) - (TAMB))/ΘJA Where: The value of ΘJA for the SOT23 package is 220ºC/W in a typical PC-board mounting. The value of ΘJA for the WLP package is 225ºC/W. Note: Exceeding the maximum allowable dissipation will cause excessive device temperature and the regulator will go into thermal shutdown.
