A103
600mA CMOS
LOW DROPOUT REGULATOR
DESCRIPTION
The A103 is a positive, low dropout regulator rated
for 600mA output current, making it ideal for battery
applications. Low power consumption and high accuracy
is achieved through CMOS technology and internal
trimmed reference voltage.
The space-saving SOT-89, and SOT-223 packages
are attractive for "Pocket" and "Hand Held" applications.
The A103 consists of a high-precision voltage
reference, and an error correction circuit. The fast
transient response is an outstanding feature for
applications with various loads.

Note: TJ = TA + (PD × θJA)
PD: Power dissipation.
θJA: Thermal resistance from Junction to Ambient.
For SOT-89 package, θJT = 25°C / W.
TJ = TTAB + (PD × θJT)
TTAB: Tab temperature.
θJT: Thermal resistance from junction to tab of the package.
The θJA numbers are guidelines for the thermal performance of the device/PC-board system.
All of the above assume no ambient airflow.
