Description

The TPL820 series products are high performance and low

dropout linear regulators. The TPL820 series products support

maximum 42 V input voltage and 200 mA output current with low

quiescent current and high PSRR. The TPL820 series products

is stable with 2.2 μF or higher output capacitor, and 4.7 μF

ceramic capacitor is recommended.

The TPL820 series products have a high PSRR with 73 dB at

100 Hz. This feature makes TPL820 series products very

suitable for power-sensitive applications with high noise from

previous stage power supply. 2 μA ultra-low quiescent current

makes the TPL820 series products ideal choices for portable

devices with battery power supply. Current-limit and thermal

overload protection circuits improves the reliability under heavy

load conditions.

The TPL820 series products provide fixed output voltage

options from 1.2 V to 5 V with ±2% voltage accuracy over

operating conditions. The TPL820 series products are

guaranteed over ambient temperature range from –40°C to

+85°C.
