TA48M025,03,033,0345,04,05F TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA48M025F,TA48M03F,TA48M033F, TA48M0345F,TA48M04F,TA48M05F 2.5 V, 3 V, 3.3 V, 3.45 V, 4 V, 5 V Three-Terminal Low Dropout Voltage Regulator The TA48M**F series consists of fixed-positive-output, low dropout regulators with an output current of 500 mA (max). In response to the need for low voltage devices, the series offers devices with low output voltages of 2.5 V, 3 V, 3.3 V, 3.45 V, and 4 V, which are not included in the existing TA78DM**S series (0.5 A low dropout). TA48M**F (S) Features • Maximum output current of 0.5 A • Low standby current: 0.8 mA (typ.) • Low dropout voltage: 0.65 V (max) @IOUT = 0.5 A • Protection function: overheat/overcurrent/overvoltage/reversed power supply connections. • PW-Mold package: Surface-mount type for reflow soldering is also supported.

The capacitances should be determined experimentally. In particular, adequate investigation should be made so that there is no problem even in high or low temperatures. Note: Depending on the type of capacitor being used to connect to the output, characteristics (capacitance, frequency and others) may decline and the output may oscillate. To prevent this, Toshiba recommends a tantalum electrolytic capacitor that has a small fluctuation in capacitance characteristics. 6 2007-03-16 TA48M025,03,033,0345,04,05F 7 2007-03-16 TA48M025,03,033,0345,04,05F 8 2007-03-16 TA48M025,03,033,0345,04,05F 9 2007-03-16 TA48M025,03,033,0345,04,05F 1.7±0.2 Package Dimensions Weight: 0.36 g (typ.) 10 2007-03-16 TA48M025,03,033,0345,04,05F Package Dimensions HSOP3-P-2.30A Weight: 0.36 g (typ.) 11 2007-03-16 TA48M025,03,033,0345,04,05F RESTRICTIONS ON PRODUCT USE 20070701-EN • The information contained herein is subject to change without notice. • TOSHIBA is continually working to improve the quality and reliability of its products.
