DATASHEET ISL9003A FN6299 Rev 5.00 Low Noise LDO with Low I and High PSRR Q July 18, 2014 ISL9003A is a high performance single low noise, high Features PSRR LDO that delivers a continuous 150mA of load High Performance LDO with 150mA Continuous Output current. It has a low standby current and is stable with 1F of MLCC output capacitance with an ESR of up to 200m . Excellent Transient Response to Large Current Steps Excellent Load Regulation: The ISL9003A has a very high PSRR of 90dB and output <0.1% voltage change across full range of load current noise is 20V (typical). When coupled with a no load RMS quiescent current of 31A (typical), and 0.5A shutdown Very High PSRR: >90dB at 1kHz current, the ISL9003A is an ideal choice for portable wireless Wide Input Voltage Capability: 2.3V to 6.5V equipment. Extremely Low Quiescent Current: 31A The ISL9003A comes in many fixed voltage options with 1.8% output voltage accuracy over temperature, line and Low Dropout Voltage: Typically 200mV at 150mA load. Other output voltage options are available on request. Low Output Noise: Typically 20V at 100A (1.5V) RMS Stable with 1F to 4.7F Ceramic Capacitors Pinouts ISL9003A Shutdown Pin Turns Off LDO with 1A (max) Standby (5 LD SC-70) Current TOP VIEW Soft-start Limits Input Current Surge During Enable VO VIN 1 5 Current Limit and Overheat Protection GND 2 1.8% Accuracy Over all Operating Conditions EN 3 4 CBYP 5 Ld SC-70 Package or 6 Ld TDFN Package -40C to +85C Operating Temperature Range Pb-Free (RoHS compliant) ISL9003A (6 LD 1.6x1.6 TDFN) Applications TOP VIEW PDAs, Cell Phones and Smart Phones VO 1 6 VIN Portable Instruments, MP3 Players 5 GND 2 5 NC Handheld Devices Including Medical Handhelds CBYP 3 4 EN FN6299 Rev 5.00 Page 1 of 12 July 18, 2014ISL9003A Ordering Information V VOLTAGE PACKAGE O PART NUMBER (V) TEMP.
