FEATURES  
DESCRIPTION  
2
24-V Maximum Input Voltage  
The TPS715xx low-dropout (LDO) voltage regulators  
offer the benefits of high input voltage, low-dropout  
voltage, low-power operation, and miniaturized  
packaging. The devices, which operate over an input  
range of 2.5 V to 24 V, are stable with any capacitor  
(0.47 µF). The low dropout voltage and low  
quiescent current allow operations at extremely low  
power levels. Therefore, the devices are ideal for  
powering battery management ICs. Specifically, since  
the devices are enabled as soon as the applied  
voltage reaches the minimum input voltage, the  
output is quickly available to power continuously  
operating battery charging ICs.  
Low 3.2-µA Quiescent Current at 50 mA  
Stable With Any Capacitor (0.47 µF)  
50-mA Low-Dropout Regulator  
Available in 1.8 V, 1.9 V, 2.3 V, 2.5 V, 3.0 V,  
3.3 V, 3.45 V, 5.0 V, and  
Adjustable (1.2 V to 15 V)  
Designed to Support MSP430 Families:  
1.9-V version ensured to be higher than  
minimum VIN of 1.8 V  
2.3-V version ensured to meet 2.2-V  
minimum VIN for FLASH on MSP430F2xx  
The usual PNP pass transistor has been replaced by  
a PMOS pass element. Because the PMOS pass  
element behaves as a low-value resistor, the low  
dropout voltage, typically 415 mV at 50 mA of load  
current, is directly proportional to the load current.  
The low quiescent current (3.2 µA typically) is stable  
over the entire range of output load current (0 mA to  
50 mA).  
3.45-V version ensured to be lower than  
maximum VIN of 3.6 V  
Wide variety of fixed output voltage options  
to match VIN to the minimum required for  
desired MSP430 speed  
Minimum/Maximum Specified Current Limit  
5-Pin SC70/SOT-323 (DCK) Package  
–40°C to +125°C Specified Junction
