General Description
The TD5820 is a high performance positive voltage
regulator designed for use in applications requiring very
low Input voltage and very low dropout voltage at up to 2
amps. It operates with a VIN as low as 1.6V and VPP
voltage 5V with output voltage programmable as low as
0.8V. The TD5820 features ultra low dropout, ideal for
applications where VOUT is very close to VIN.
Additionally, the TD5820 has an enable pin to further
reduce power dissipation while shutdown. The TD5820
provides excellent regulation over variations in line,
load and temperature. The TD5820 provides a power OK
signal to indicate if the voltage level of VO reaches
92% of its rating value.
The TD5820 is available in the power SOP-8 PP package. It is available with 1.2V, 1.5V, 1.8V and 2.5V internally preset outputs that are also adjustable using
external resistors.
