description  
TPS7225  
The TPS72xx family of low-dropout (LDO) voltage  
regulators offers the benefits of low-dropout  
voltage, micropower operation, and miniaturized  
packaging. These regulators feature extremely  
low dropout voltages and quiescent currents  
compared to conventional LDO regulators.  
Offered in small-outline integrated-circuit (SOIC)  
packages and 8-terminal thin shrink small-outline  
(TSSOP), the TPS72xx series devices are ideal  
for cost-sensitive designs and for designs where  
board space is at a premium.

A combination of new circuit design and process  
innovation has enabled the usual pnp pass  
transistor to be replaced by a PMOS device.  
Because the PMOS pass element behaves as a  
low-value resistor, the dropout voltage is very low  
– maximum of 85 mV at 100 mA of load current  
(TPS7250) – and is directly proportional to the  
load current (see Figure 1). Since the PMOS pass

element is a voltage-driven device, the quiescent current is very low (300 µA maximum) and is stable over the  
entire range of output load current (0 mA to 250 mA). Intended for use in portable systems such as laptops and  
cellular phones, the low-dropout voltage and micropower operation result in a significant increase in system  
battery operating life.  
The TPS72xx also features a logic-enabled sleep mode to shut down the regulator, reducing quiescent current  
to 0.5 µA maximum at T = 25°C. Other features include a power-good function that reports low output voltage  
J
and may be used to implement a power-on reset or a low-battery indicator.  
§
The TPS72xx is offered in 2.5-V, 2.75-V , 3-V, 3.3-V, 4.85-V, and 5-V fixed-voltage versions and in an adjustable  
version (programmable over the range of 1.2 V to 9.75 V). Output voltage tolerance is specified as a maximum  
of 2% over line, load, and temperature ranges (3% for adjustable version).  
This device is in the product preview stage of development. Please contact the local TI sales office for availability.
