STMicroelectronics Fixed LDO Voltage Regulator, 3.3V / 1A, TO-252-3
STMicroelectronics 3.3V / 1A fixed LDO voltage regulator in TO-252-3 package. Low 1.15V dropout, 4.5-10V input, for stable power.
The STMicroelectronics Fixed LDO Voltage Regulator is a robust and reliable component designed for precise voltage regulation in a compact, surface-mount package. This positive output regulator delivers a stable 3.3V from an input voltage range of 4.5V to 10V, making it an essential part of power management circuits where clean, dependable power is critical.
A key feature is its low dropout voltage of 1.15V, which allows the regulator to continue providing the correct output even when the input voltage dips close to the desired output level, improving efficiency and extending battery life in portable applications. With a maximum output current of 1A, it is capable of powering a wide range of microcontrollers, sensors, and other low-power digital circuits.
Housed in a TO-252-3 (DPAK) package, it offers excellent thermal performance for its power handling capability. The device is specified for a broad operating temperature range from 0°C to 125°C, ensuring reliable performance in diverse environmental conditions, from consumer electronics to industrial settings.
Applications
This fixed linear regulator is ideal for post-regulation in switch-mode power supplies, battery-powered devices, and as a local power source for noise-sensitive digital and analogue circuits on PCBs. Its stability and current capability make it a go-to choice for designers requiring a simple, effective voltage regulation solution.
