1.5uA Low Power Mosfet Transistor AS1360-33-T Positive Voltage Regulator
AS1360 1.5µA Low-Power, Positive Voltage Regulator
1 General Description
The AS1360 low-power, positive voltage regulator was designed to deliver up to 250mA while consuming only 1.5µA of quiescent current. The device is available in fixed output voltages of 1.8, 2.1, 2.5, 3.0, 3.3, and 5.0V. The device features integrated short-circuit and overcurrent protection. The wide input voltage range, low-dropout voltage, and high-accuracy output voltage makes the device perfectly suited for 2- and 3-cell battery-powered and portable applications. The low dropout voltage (650mV) prolongs battery life and allows high current in small applications when operated with minimum input-to-output voltage differentials. The device features very stable output voltage (using only 1µF tantalum or aluminum-electrolytic capacitors), strict output voltage regulation tolerances (±0.5%), and excellent line-regulation. The AS1360 is available in a 3-pin SOT23 package. Figure 1. AS1360 - Block Diagram

Pin Descriptions
| Pin Number | Pin Name | Description |
| 1 | GND | Ground. This pin should be connected to the negative side of the output and the negative terminal of the input capacitor. No high-current flows out of this pin, only bias current (1.5µA, typ). Note: Voltage drops between this pin and the negative side of the load should be minimized. |
| 2 | VOUT | Regulated Output Voltage. This pin should be connected to the positive side of the load and the positive terminal of the output capacitor. Current flowing out of this pin is equivalent DC load current. Note: The positive side of the output capacitor should be mounted as close as is practical to this pin. |
| 3 | VIN | Unregulated Input Voltage. This pin should be connected to the positive terminal of the input capacitor. Note: The input capacitor should be mounted as close as is practical to this pin. |
