SemiconductorThe Ascend Semiconductor ASPL7533DI-R Linear Voltage Regulator (LDO) ROHS with SOT-89-3 is a low voltage, low dropout current regulator with a low quiescent current ideal for battery powered applications and energy efficient designs. This chip features a wide input voltage range of 2.7V to 5.5V making it suitable for use in battery powered systems with Li-Ion and Li-Polymer battery cells or from a widely available +5V supply. It is capable of delivering up to 1A of output current and can operate over a wide range of temperature between -40°C to +125°C. It features low dropout voltage, low operating current, good line and load regulation, low output noise, and thermal shutdown protection, making it suitable for a wide range of applications including personal navigation systems and portable medical devices. The RoHS-compliant package is a SOT-89-3 that offers an enhanced thermal and electromagnetic signature.
