LD29150DT33R Description

Short technical summary and product information.

The LD29150DT33R is a fixed-output linear voltage regulator from STMicroelectronics, designed to provide a stable 3.3V output with a maximum current of 1.5A. It operates with an input voltage up to 14V and features a low dropout voltage of 700mV maximum at full load. The regulator offers excellent line and load regulation of 0.5% and 1% respectively, and a PSRR of 67dB at 120Hz, making it suitable for noise-sensitive applications.

 

With a quiescent current of 40mA and an input bias current of 15mA, the device maintains efficiency in low-power designs. The reference voltage is 1.2423V, and the voltage regulation accuracy is 1%. The LD29150DT33R is specified for an operating temperature range of -40°C to +125°C, allowing use in harsh environments.

 

The regulator is housed in a TO-252 (DPAK) surface-mount package with dimensions of 6.6mm x 6.2mm x 2.4mm. It is supplied on tape and reel with a factory pack quantity of 2500 units, suitable for automated assembly processes.
