Low dropout voltage: 150 mV at 200 mA load
Figure 1. TSOT ADP151-EP with Fixed Output Voltage, 3.3 V
Accuracy over line, load, and temperature: −2.5%/+3% PSRR performance of 70 dB at 10 kHz Current-limit and thermal overload protection Internal pull-down resistor on EN input 5-lead TSOT package Enhanced processing (EP) for −55°C to +125°C operation APPLICATIONS RF, VCO, and PLL power supplies Portable and battery-powered equipment Post dc-to-dc regulation Portable medical devices Aeronautic and military operating temperature environment GENERAL DESCRIPTION
The ADP151-EP is an ultralow noise, low dropout linear The ADP151-EP is specifically designed for stable operation regulator that operates from 2.2 V to 5.5 V and provides up to with tiny 1 µF, ±30% ceramic input and output capacitors to 200 mA of output current. The low 150 mV dropout voltage at meet the requirements of high performance, space constrained 200 mA load improves efficiency and al ows operation over a applications. wide input voltage range. The ADP151-EP is capable of 16 fixed output voltage options, Using an innovative circuit topology, the ADP151-EP achieves ranging from 1.1 V to 3.3 V. ultralow noise performance without the necessity of a bypass Short-circuit and thermal overload protection circuits prevent capacitor, making it ideal for noise-sensitive analog and RF damage in adverse conditions. The ADP151-EP is available in a applications. The ADP151-EP also achieves ultralow noise tiny 5-lead TSOT package. performance without compromising PSRR or transient line and load performance. The low 265 μA of quiescent current Additional application and technical information can be found at 200 mA load makes the ADP151-EP suitable for battery- in the ADP151 data sheet. operated portable equipment. The ADP151-EP also includes an internal pull-down resistor on the EN input.
