HT7333-LDO 3.3V LINEAR VOLTAGE REGULATORS

The HT7333A is a low dropout voltage regulator (LDO) designed for low power consumption and high efficiency. It is capable of delivering up to 100mA output current with a fixed 3.3V output voltage. Its small SOT-89 package makes it suitable for portable devices and other applications where space is limited.

The HT7333 is a high efficiency 3.3V linear voltage regulator. It provides a regulated voltage of 3.3V with very low losses because of its low quiescent current and low drop-out voltage. Quiescent current is the current that gets leaked out through our regulator even when no load is connected this current is only of 8uA for HT7333.

Dropout voltage is the voltage difference between the Input voltage and output voltage, which is also very less for a HT733 IC. Both these characteristics helps us to extract all the juice from a 3.7V Lithium coin cell like RJD2450, hence these IC’s are widely used along with it.
