General Description
AP2203 General Description
The AP2203 is a 150mA ULDO regulator, which provides ultra low dropout voltage (typically 165mV at= 150mA), very low quiescent current (1A maximum) in shutdown mode and excellent power supply ripple rejection (PSRR 75dB at 100Hz) in battery powered applications, such as handsets and PDAs and in noise sensitive applications, such as RF electronics.
The AP2203 also features an undervoltage monitor with an error flag output, logic compatible enable/shutdown control inputs, a low power shutdown mode for extended battery life, over current protection, over temperature protection as well as reversed-battery protection.
The AP2203 has 2.5V, 3.0V and 3.3V versions.
The AP2203 is available in space saving 5-pin SOT- 23-5 package.
AP2203 Maximum Ratings
| Parameter | Symbol | Value | Unit |
| Supply Input Voltage | VIN | 15 | V |
| Enable Input Voltage | VEN | 15 | V |
| Power Dissipation | PD | Internally Limited (Thermal Protection) | W |
| Lead Temperature (Soldering, 5sec) | TLEAD | 260 | °C |
| Storage Temperature | TSTG | -65 to 150 | °C |
| ESD (Machine Model) | 300 | V | |
| Thermal Resistance (No Heatsink) | JA | 200 | °C/W |
These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated
under "Recommended Operating Conditions" is not implied. Exposure to "Absolute Maximum Ratings" for extended periods
may affect device reliability.
