description
NC – No internal connection
† _{SENSE – Fixed voltage options only}
The TPS73xx devices are members of a family of
micropower low-dropout (LDO) voltage regulators.
(TPS7325, TPS7330, TPS7333, TPS7348, and TPS7350)
‡ _{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.
