ISL9011A ® Data Sheet January 30, 2007 Dual LDO with Low Noise, Low IQ, and High PSRR ISL9011A is a high performance dual LDO capable of sourcing 150mA current from Channel 1 and 300mA from Channel 2. The device has a low standby current and highPSRR and is stable with output capacitance of 1μF to 10μF with ESR of up to 200mΩ. A reference bypass pin allows an external capacitor for adjusting a noise filter for low noise and high PSRR applications. The quiescent current is typically only 45µA with both LDO’s enabled and active. Separate enable pins control each individual LDO output. When both enable pins are low, the device is in shutdown, typically drawing less than 0.1μA.

High performance is achieved through a circuit that delivers fast transient response to varying load conditions. In a quiescent condition, the ISL9011A adjusts its biasing to achieve the lowest standby current consumption. The device also integrates current limit protection, smart thermal shutdown protection, staged turn-on and soft-start. Smart Thermal shutdown protects the device against overheating. Staged turn-on and soft-start minimize start-up input current surges without causing excessive device turnon time. Power Control The ISL9011A has two separate enable pins (EN1 and EN2) to individually control power to each of the LDO outputs. When both EN1 and EN2 are low, the device is in shutdown 9 VOLTAGE REFERENCE GENERATOR mode. During this condition, all on-chip circuits are off, and the device draws minimum current, typically less than 0.1μA. When one or both of the enable pins are asserted, the device first polls the output of the UVLO detector to ensure that VIN voltage is at least about 2.1V. Once verified, the device initiates a start-up sequence. During the start-up sequence, trim settings are first read and latched. Then, sequentially, the bandgap, reference voltage and current generation circuitry power-up. Once the references are stable, a fast-start circuit quickly charges the external reference bypass capacitor (connected to the CBYP pin) to the proper operating voltage. After the bypass capacitor has been charged, the LDO’s power-up. If EN1 is brought high, and EN2 goes high before the VO1 output stabilizes, the ISL9011A delays the VO2 turn-on until the VO1 output reaches its target level. If EN2 is brought high, and EN1 goes high before VO2 starts its output ramp, then VO1 turns on first and the ISL9011A FN6437.0 January 30, 2007 ISL9011A delays the VO2 turn-on until the VO1 output reaches its target level. If EN2 is brought high, and EN1 goes high after VO2 starts its output ramp, then the ISL9011A immediately starts to ramp up the VO1 output. If both EN1 and EN2 are brought high at the same time, the VO1 output has priority, and is always powered up first. During operation, whenever the VIN voltage drops below about 1.8V, the ISL9011A immediately disables both LDO outputs. When VIN rises back above 2.1V, the device reinitiates its start-up sequence and LDO operation will resume automatically. Reference Generation The reference generation circuitry includes a trimmed bandgap, a trimmed voltage reference divider, a trimmed current reference generator, and an RC noise filter. The filter includes the external capacitor connected to the CBYP pin. A 0.01μF capacitor connected CBYP implements a 100Hz lowpass filter, and is recommended for most high performance applications. For the lowest noise application, a 0.1μF or greater CBYP capacitor should be used. This filters the reference noise to below the 10Hz to 1kHz frequency band, which is crucial in many noise-sensitive applications. The bandgap generates a zero temperature coefficient (TC) voltage for the reference divider. The reference divider provides the regulation reference and other voltage references required for current generation and over-temperature detection. The current generator outputs references required for adaptive biasing as well as references for LDO output current limit and thermal shutdown determination. 10 LDO Regulation and Programmable Output Divider The LDO Regulator is implemented with a high-gain operational amplifier driving a PMOS pass transistor. The design of the ISL9011A provides a regulator that has low quiescent current, fast transient response, and overall stability across all operating and load current conditions. LDO stability is guaranteed for a 1μF to 10μF output capacitor that has a tolerance better than 20% and ESR less than 200mΩ. The design is performance-optimized for a 1μF capacitor. Unless limited by the application, use of an output capacitor value above 4.7μF is not recommended as LDO performance improvement is minimal. Soft-start circuitry integrated into each LDO limits the initial ramp-up rate to about 30μs/V to minimize current surge. The ISL9011A provides short-circuit protection by limiting the output current to about 475mA. Each LDO uses an independently trimmed 1V reference. An internal resistor divider drops the LDO output voltage down to 1V. This is compared to the 1V reference for regulation. The resistor division ratio is programmed in the factory. Overheat Detection The bandgap outputs a proportional-to-temperature current that is indicative of the temperature of the silicon. This current is compared with references to determine if the device is in danger of damage due to overheating. When the die temperature reaches about +145°C, one or both of the LDO’s momentarily shut down until the die cools sufficiently. In the overheat condition, only the LDO sourcing more than 50mA will be shut off. This does not affect the operation of the other LDO. If both LDOs source more than 50mA and an overheat condition occurs, both LDO outputs are disabled. Once the die temperature falls back below about +110°C, the disabled LDO(s) are re-enabled and soft-start automatically takes place.
