The HA178L00 series is a three-terminal fixed output voltage regulator that can be used as stabilized power sources and Zener diodes. It features a maximum output current of 150mA, maximum power dissipation of 800mW, overcurrent protection, and temperature protection circuit.
The document describes the HA178L00 series of three-terminal fixed output voltage regulators manufactured by Hitachi. These devices are designed to be used as stabilized power sources or Zener diodes due to their small outline package availability.
Key features include a maximum output current of 150 mA, large maximum power dissipation up to 800 mW, overcurrent protection, and an integrated temperature protection circuit. The series offers various standard output voltages ranging from 2.5V to 15V in both TO-92M and UPAK packages.
| Maximum output current | 150 mA (Tj= 25°C) |
|---|---|
| Large maximum power dissipation | 800 mW |
| Operating ambient temperature (TO-92M) | -20 to +75 °C |
| Operating ambient temperature (UPAK) | -20 to +85 °C |
| Storage temperature | -55 to +150 °C |
The maximum output current is 150 mA when the junction temperature (Tj) is 25°C.
The UPAK package operates between -20 and +85 °C.
