5.4V DC linear voltage regulator, designed for replacing the 5.4V mercury batteries used in vintage electronics gear, like Federal 230 gage amplifiers. TPS7A2501 regulator IC, with resistors to set the output voltage to 5.4VDC.
- Max input voltage: 18V
- Max current: 300mA
- Low dropout (50-340mV, depending on current)
- Thermal shutdown and overcurrent protection
- Ultra low quiescent current (approx. 3.5uA on 7.5V input)
Because of the ultra low quiescent current, this regulator may be left connected without excessive drain, making it perfect for low-power vintage gear.
