CS5204-5GT3 is listed in the Voltage Regulators - Linear, Low Drop Out (LDO) Regulators range at ChipApex. The manufacturer field lists onsemi. Its product description is IC REG LINEAR 5V 4A TO220-3. Review the specifications below when checking this part for your BOM.
The onsemi CS5204-5GT3 is a linear voltage regulator IC providing a fixed positive output of 5.0 V with a maximum output current of 4.0 A. Housed in a TO-220-3 straight package, it features a maximum input voltage of 17 V and a typical dropout voltage of 1.2 V at full load. The device includes overcurrent protection and offers a power supply rejection ratio (PSRR) of 75 dB at 120 Hz.
Verify the exact suffix GT3 corresponds to the TO-220-3 straight package variant. Confirm the fixed 5V output specification matches the design requirement, as other suffixes may indicate adjustable or different voltage options. Ensure thermal management plans account for the 4A output capability and associated power dissipation in the target application environment.
Select this component when a stable 5V rail is required from an input source up to 17V. The 4A current rating suits moderate power applications. Consider the TO-220-3 package for through-hole mounting and ease of heatsinking. Compare PSRR and dropout characteristics against alternative regulators if low-noise performance is critical.
This part belongs to the CS5204 series of linear regulators from onsemi. The series includes adjustable versions and other fixed voltage outputs like 3.3V. It is designed for general-purpose power management tasks where simplicity and reliability are prioritized over high efficiency switching solutions.
Direct substitutes include other 5V 4A linear regulators in TO-220 packages such as the LM340T-5.0 from Texas Instruments or similar equivalents from STMicroelectronics, provided pinouts and thermal characteristics are compatible.
