High performance is achieved through a circuit that delivers fast transient response to varying load conditions. In a quiescent condition, the ISL9003A adjusts its biasing to achieve the lowest standby current consumption. 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 device also integrates current limit protection, smart thermal shutdown protection, and soft-start. Smart Thermal shutdown protects the device against overheating. Soft-start minimizes start-up input current surges without causing excessive device turn-on time. Power Control The ISL9003A has an enable pin, (EN), to control power to the LDO output. When EN is low, the device is in shutdown mode. In this condition, all on-chip circuits are off, and the device draws minimum current, typically less than 0.3µA. When the EN pin goes high, the device first polls the output of the UVLO detector to ensure that VIN voltage is at least 2.1V (typical). 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 turn-on. Once the references are stable, the LDO powers-up. During operation, whenever the VIN voltage drops below about 1.84V, the ISL9003A immediately disables the LDO output. When VIN rises back above 2.1V (assuming the EN pin is high), the device re-initiates its start-up sequence and LDO operation resumes automatically. Submit Document Feedback 9 The bandgap generates a zero temperature coefficient (TC) voltage for the regulator reference and other voltage references required for current generation and over-temperature detection. A current generator provides references required for adaptive biasing as well as references for LDO output current limit and thermal shutdown determination. 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 ISL9003A 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 4.7µF output capacitor that has a tolerance better than 20% and ESR less than 200m. 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 FN6299.5 July 18, 2014 ISL9003A about 30µs/V to minimize current surge. The ISL9003A provides short-circuit protection by limiting the output current to about 265mA (typ). The LDO uses an independently trimmed 1V reference as its input. 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 +140°C, the LDO momentarily shuts down until the die cools sufficiently. In the overheat condition, if the LDO sources more than 50mA it will be shut off. Once the die temperature falls back below about +110°C, the disabled LDO is re-enabled and soft-start automatically takes place. Exposed Thermal Pad The ISL9003A with µTDFN package has an exposed thermal pad at the bottom side of the package. The PCB layout should connect the exposed pad to some copper on the component layer for a good thermal conductivity. Since the copper area on the component layer is limited by the surrounding pins of the package, it is more effective to use some thermal vias to conduct the heat to other copper layers if possible. Electrically the copper and vias connecting to the exposed pad should be isolated from any other pin connection, they are strictly for thermal enhancement purpose.
