1FEATURES DESCRIPTIONThe LP3986isa 150 mA dual low dropout regulator
Miniature 8-I/O DSBGA Package designed for portable and wireless applications with
• Stable With1µF Ceramic and High Quality demanding performance and board space
Tantalum Output Capacitors requirements.
Fast Turn-on The LP3986 is stable witha small1µF ±30%
• Two Independent Regulators ceramic output capacitor requiring smallest possible
board space.
• Logic Controlled Enable Over Current and Thermal Protection The LP3986's performanceis optimized for battery
powered systemsto deliver ultra low noise, extremely
APPLICATIONS low dropout voltage and low quiescent current
independentof load current. Regulator ground current
• CDMA Cellular Handsets increases very slightlyin dropout, further prolonging
• GSM Cellular Handsets the battery life. Optional external bypass capacitor
reduces the output noise further without slowing down
• Portable Information Appliancesthe load transient response. Fast start-up timeis
• Portable Battery Applications achieved by utilizinga speed-up circuit that actively
pre-charges the bypass capacitor. Power supply
rejectionis better than 60 dBat low frequencies and dBat 10 kHz. High power supply rejectionis
maintained at low input voltage levels commonto
battery operated circuits.
The LP3986is available ina DSBGA package.
Performanceis specified fora −40°C to +125°C
temperature range. For single LDO applications,
please referto the LP3985 datasheet.
