3-TERMINAL 0.1A POSITIVE VOLTAGE REGULATOR

DESCRIPTION

The 78L10G family is monolithic fixed voltage regulator integrated circuit. They are suitable for applications that required supply current up to 100mA.

FEATURES

Output current up to 100mA Fixed output voltage of 10V available Thermal overload shutdown protection Short circuit current limiting MARKING INFORMATION PACKAGE VOLTAGE CODE MARKING SOT-89 10:10V 78L10 123 78L10G 321 1 of 4 REV.08

PARAMETER SYMBOL RATINGS UNIT Input Voltage V IN 35 V Output Current I OUT 100 mA Power Dissipation P D 350 mW Junction Temperature T J +150 °C Operating Temperature (Note 2) T OPR -40 ~ +125 °C Storage Temperature T STG -55 ~ +150 °C Notes: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged. Absolute maximum ratings are stress ratings only and functional device operation is not implied. 2. It is guarantee by design, not 100% be tested.

The Maximum steady state usable output current is dependent on input voltage, heat sinking, lead length of the package and copper pattern of PCB. 2. Power dissipation <0.5W 78L10G 2 of 4 REV.08

Notes: 1. To specify an output voltage, substitute voltage value for "XX". 2. Bypass capacitors are recommended for optimum st ability and transient response and should be located as close as possible to the regulators.
