The TPS73xx devices are members of a family of
micropower low-dropout (LDO) voltage regulators.
‡
FB – Adjustable version only (TPS7301)
They are differentiated from the TPS71xx and TPS72xx LDOs by their integrated delayed microprocessor-reset

function. If the precision delayed reset is not required, the TPS71xx and TPS72xx should be considered.

The D and PW packages are available taped and reeled. Add an R suffix to device type (e.g., TPS7350QDR). The TPS7301Q is programmable
using an external resistor divider (see application information). The chip form is tested at 25°C.
§
¶
The TPS7325 has a tolerance of ±3% over the full temperature range.
The TPS71xx and the TPS72xx are 500-mA and 250-mA output regulators respectively, offering performance similar to that of the TPS73xx but
without the delayed-reset function. The TPS72xx devices are further differentiated by availability in 8-pin thin-shrink small-outline packages
(TSSOP) for applications requiring minimum package size.
