GOODWORK 78L05 100mA 49dB@(120Hz) Fixed 5V Positive 30V SOT-89 Voltage Regulators (LDO) SMD
The GOODWORK 78L05 is a highly efficient low-dropout (LDO) voltage regulator that delivers a stable fixed 5V output from an input voltage range of 6V to 30V. With a maximum output current of 100mA, this voltage regulator is perfect for powering low-power devices that require stable and noise-free operation.
This LDO features a dropout voltage of 1.2V and a power supply rejection ratio (PSRR) of 49dB at 120Hz, ensuring minimal noise interference in sensitive applications such as audio circuits and communication systems. Its compact SOT-89 package makes it ideal for space-constrained designs while providing high performance.
Features:
- Fixed 5V output voltage for consistent power delivery.
- PSRR of 49dB @ 120Hz for effective noise suppression.
- Supports up to 100mA output current for low-power devices.
- Dropout voltage of 1.2V for improved power efficiency.
- Wide input voltage range from 6V to 30V for versatility.
- Compact SOT-89 package for space-efficient designs.
