AS1363
500mA Low-Dropout Linear Voltage Regulator
1 General Description
The AS1363 is a low-dropout linear regulator that operates from a
+2.0V to +5.5V supply and delivers a guaranteed 500mA load
current with low 150mV dropout.
The device is available in two versions
(see Table 1)
. One version
has a high-accuracy output with a preset voltage (1.2V, 1.5V, 1.8V,
3.0V, 3.3V, or 4.5V). This voltage is internally trimmed and also offers
a Bypass pin. With a capacitor connected to this Bypass pin, the
PSRR and the Noise performance is improved.
At the other version the output voltage is user-adjustable (1.2V to
5.3V) and offers an SET pin for setting the output voltage.
Table 1. Standard Products
A low supply current (65μA typ.) at maximum load is making the
device ideal for portable battery-operated equipment.
Other features are included such as an active-low open-drain reset
output that indicates when the output is out of regulation, a low-
current (30nA typ.) shutdown mode, an integrated short-circuit and a
thermal shutdown protection.
When in shutdown, a 5k
(typ) discharge path is connected
between the output pin and ground. The AS1363 is available in a 6-
pin SOT23 package.
