SNVS087AC –OCTOBER 2000–REVISED MAY 2013  
LP3985 Micropower, 150mA Low-Noise Ultra Low-Dropout CMOS Voltage Regulator  
Check for Samples: LP3985

FEATURES  
DESCRIPTION  
The LP3985 is designed for portable and wireless  
applications with demanding performance and space  
requirements.  
2
•
Miniature 5-I/O DSBGA and USON Package  
Logic Controlled Enable  
•
•
Stable with Ceramic and High Quality  
Tantalum Capacitors  
The LP3985 is stable with a small 1µF ±30% ceramic  
or high-quality tantalum output capacitor. The DSBGA  
requires the smallest possible PC board area - the  
total application circuit area can be less than 2.0mm x  
2.5mm, a fraction of a 1206 case size.  
•
•
Fast Turn-on  
Thermal Shutdown and Short-Circuit Current  
Limit  
The LP3985's performance is optimized for battery  
powered systems to deliver ultra low noise, extremely  
low dropout voltage and low quiescent current.  
Regulator ground current increases only slightly in  
dropout, further prolonging the battery life.  
APPLICATIONS  
•
•
•
•
CDMA Cellular Handsets  
Wideband CDMA Cellular Handsets  
GSM Cellular Handsets  
An optional external bypass capacitor reduces the  
output noise without slowing down the load transient  
response. Fast startup time is achieved by utilizing an  
internal power-on circuit that actively pre-charges the  
bypass capacitor.  
Portable Information Appliances  
KEY SPECIFICATIONS

2.5 to 6.0V Input Range  
Power supply rejection is better than 50dB at low  
frequencies and starts to roll off at 1kHz. High power  
supply rejection is maintained down to low input  
voltage levels common to battery operated circuits.  
150mA Verified Output  
50dB PSRR at 1kHz @ VIN = VOUT + 0.2V  
≤1.5μA Quiescent Current when Shut Down  
Fast Turn-On time: 200μs (typ.)  
The device is ideal for mobile phone and similar  
battery powered wireless applications. It provides up  
to 150mA, from a 2.5V to 6V input. The LP3985  
consumes less than 1.5µA in disable mode and has  
fast turn-on time less than 200µs.  
100mV Maximum Dropout with 150mA Load  
30μVrms Output Noise (typ.) Over 10Hz to  
100kHz
