50mA High-
Voltage Micro-power LDO in MSOP
PRELIMINARY TECHNICAL DATA
FEATURES
Wide Input
Voltage Range: 4V to 28V Low Quiescent Current: 25µA ±1% Initial Accuracy Very Low Dropout
Voltage: 300 mV @ 50mA Fixed 3.3V and 5V
Voltage Options Adjustable Output from 1.2V to 5.0V Optimized for Small 1µF Ceramic
Capacitors Short Circuit Protection Thermal Overload Protection Spacing-saving Thermally Enhanced MSOP package
ADP1720
GENERAL DESCRIPTION
The ADP1720 is a high-
voltage, micro-power, low dropout linear regulator. Designed for robust operation, the ADP1720 includes current limiting and short-circuit protection, and thermal overload protection . With just 25µA of quiescent supply current and a micro-power shutdown mode, this device is ideal for applications that require low quiescent current. The small thermally-enhanced MSOP package and 1µF ceramic output capacitor provides a compact solution with low thermal resistance for high power dissipation. The ADP1720 is available in fixed output
voltages of 3.3V and 5V, or its output
voltage can be adjusted over a range of 1.2V to 5V. The ADP1720 operates over the -40°C to 125°C ambient temperature range.
