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 -

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. |
