ISL9008AIEFZ-T集成电路（IC）的线性+开关稳压器规格书PDF中文资料

Low Noise LDO with Low IQ, High PSRR

ISL9008A is a high performance single low noise, high PSRR LDO that delivers a continuous 150mA of load current. It has a low standby current and is stable with 1µF of MLCC output capacitance with an ESR of up to 200mΩ.

Features

• High performance LDO with 150mA continuous output

• Excellent transient response to large current steps

• Excellent load regulation: <0.1 voltage change across full range of load current

• High PSRR: 65dB at 1kHz

• Wide input voltage capability: 2.3V to 6.5V

• Very low quiescent current: 46µA

• Low dropout voltage: typically 200mV at 150mA

• Low output noise: typically 45µVRMS at 100µA (1.5V)

• Stable with 1µF to 4.7µF ceramic capacitors

• Shutdown pin turns off LDO with 1µA (max) standby current

• Soft-start limits input current surge during enable

• Current limit and overheat protection

• ±1.8 accuracy over all operating conditions

• 5 Ld SC-70 package or 6 Ld µTDFN package

• -40°C to +85°C operating temperature range

• Pb-free (RoHS compliant)

Applications

• PDAs, cell phones and smart phones

• Portable instruments, MP3 players

• Handheld devices including medical handhelds
