7533 1 Transistor Datasheet

The 7533-1 (commonly referred to as the HT7533-1) is a high-voltage, low-power CMOS Low Dropout (LDO) regulator specifically designed for 3.3V fixed output applications FarnellDigikey. While often grouped with "transistors" due to its similar TO-92 or SOT-89 packaging, it functions as a critical power management integrated circuit (PMIC).

Key Technical Specifications

• Output Voltage: 3.3V Fixed Farnell
• Input Voltage: Up to 30V (Max 33V), making it suitable for wide-input industrial use Digikey
• Output Current: Typically 100mA Alldatasheet
• Quiescent Current: Ultra-low 2.5\u03bcA to 4.0\u03bcA, ideal for battery-powered IoT devices Farnell
• Common Packages: TO-92, SOT-89, SOT-23-3, and SOT-23-5 Digikey
