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. Weight HSIP3-P-2.30B: 0.36 g (typ.) HSOP3-P-2.30A: 0.36 g ( typ.)

Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings and the operating ranges. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook ("Handling Precautions"/Derating Concept and Methods) and individual reliability data (i.e. reliability test report and estimated failure rate, etc).

Be sure to connect a capacitor near the input terminal and output terminal between both terminals and GND. 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.
