Low Dropout Voltage Regulator
The TA78DS××F series consists of fixed-positive-output voltage
regulator ICs capable of sourcing current up to 30 mA. Due to the
features of low dropout voltage and low standby current, these
devices are useful for battery-powered equipment. This series
includes built-in overcurrent protection, overheating protection,
overvoltage protection, input fault protection and excessive
transient protection circuits.
Features
z Low standby current of 600 μA typical.
z Maximum output current of 30 mA.
z Low dropout voltage of less than 0.3 V.
z Multi-protection:
Reverse connection of power supply, 60 V load dump,
z Packaged in PW-Mini (SOT-89).
Weight: 0.05 g (Typ.)
overheating protection and overcurrent protection.

The product(s) in this document (“Product”) contain functions intended to protect the Product from
temporary small overloads such as minor short-term overcurrent, overvoltage or overheating. The
protective functions do not necessarily protect Product under all circumstances. When incorporating
Product into your system, please design the system (1) to avoid such overloads upon the Product, and
(2) to shut down or otherwise relieve the Product of such overload conditions immediately upon
occurrence. For details, please refer to the notes appearing below in this document and other documents
referenced in this document.
