Unauthorized Photocopy and Duplication Prohibited ©2011 Belling All Rights Reserved 14 BL9110 1A Low Dropout, Low Quiescent Quiescent Current High PSRR CMOS Linear Regulator Applications Information The BL9110 is a low dropout CMOS-based positive voltage regulator that operates the input voltage from +2.5V to 6.0V. Output voltages are optional ranging from 1.0V to 5.0V, and can supply current up to 1.0 A. is to choose R2=20kΩ to set the divider current at 50uA, and then calculate R1 using Equation as below: Enable Function A small compensation capacitor C3 placed between VOUT and ADJ may improve the stability of the adjustable. The suggested value of this capacitor is about 10pF to 22pF. The BL9110 is shutdown by pulling the CE input low, and turn on by driving the input high. If this feature is not be used, the CE input should be floating or tied to VDD to keep the regulator on at all times. Programming the BL9110 Adjustable LDO regulator The BL9110 is available in two types, either fixed or adjustable output voltage. The output range of the adjustable types is from 1V to 5V. The output voltage of the BL9110 adjustable regulator is programmed using an external resistor divider as show in Figure as below. The output voltage is calculated using equation as below: VOUT R1 = − 1 × R 2 VREF OUTPUT VOLTAGE PROGRAMMING GUIDE OUTPUT VOLTAGTE R1 R2 1.8V 16 kΩ 20 kΩ 2.5V 30 kΩ 20 kΩ 3.3V 51 kΩ 22 kΩ 3.6V 62 kΩ 24 kΩ BL9110 Adjustable LDO regulator Programming R1 VOUT = VREF × 1 + R2 Where VREF=1V is the internal reference voltage. Resistors R1 and R2 should be chosen for approximately 50uA divider current. Lower value resistors can be used for improved noise performance, but the solution consumes more power. Higher resistor values should be avoided as leakage current at ADJ increases the output voltage error. The recommended design procedure PPMIC BU BL9110 Rev 1.2 07/2011 Thermal Protection Thermal overload protection limits total power dissipation in the BL9110. When the junction temperature exceeds TJ=165°C, the OTP circuit starts the thermal shutdown function and turns the pass element off allowing the IC to cool. The OTP circuit turns on the pass element again after IC’s junction temperature cool by 30°C, result in a pulsed output during continuous thermal www.belling.com.cn Belling Proprietary Information.

Thermal-overloaded protection is designed to protect the BL9110 in the event of fault conditions. Do not exceed the absolute maximum junction temperature rating of TJ=125°C for continuous operation. The build-in fold-back current limit protection circuit will reduce current value as output voltage drops. When output is shorted to ground, current limit is reduced to 250mA, avoiding damaging the device. Operating Region and Power Dissipation The maximum power dissipation of BL9110 depends on the thermal resistance of the case and circuit board, the temperature difference between the die junction and ambient air, and the rate of airflow. The power dissipation across the device is PD = (VDD−VOUT) ×IOUT + VDD×IQ The maximum power dissipation is: PD (MAX) = (TJ (MAX) − TA) /θJA Where TJ (MAX) is the maximum operation junction temperature 125°C, TA is the ambient temperature and the θJA is the junction to ambient thermal resistance. The GND pin of the BL9110 performs the dual function of providing an electrical connection to ground and channeling heat away. Connect the GND pin to ground using a large pad or ground plane. Capacitor Selection and Regulator Stability Like any low-dropout regulator, the external PPMIC BU BL9110 Rev 1.2 07/2011 capacitors used with the BL9110 must be carefully selected for regulator stability and performance. The BL9110 requires an output capacitor between the VOUT and GND pins for phase compensation. Using a capacitor whose value is ≥1µF on the BL9110 input and the amount of capacitance can be increased without limit. The input capacitor must be located a distance of not more than 0.5 inch from the input pin of the IC and returned to a clean analog ground. Any good quality ceramic or tantalum can be used for this capacitor. The capacitor with larger value and lower ESR (equivalent series resistance) provides better PSRR and line-transient response. The output capacitor must meet both requirements for minimum amount of capacitance and ESR in all LDO applications. The BL9110 is designed specifically to work with low ESR ceramic output capacitor in space-saving and performance consideration. In the BL9110, phase compensation is made with the output capacitor for securing stable operation even if the load current is varied. For this purpose, use a 2.2uF capacitor between VOUT pin and GND pin as close as possible. Load-Transient Considerations The BL9110 load-transient response graphs show two components of the output response: a DC shift from the output impedance due to the load current change, and the transient response. The DC shift is quite small due to the excellent load regulation of the IC. Typical output voltage transient spike for a step change in the load current from 0mA to 50mA is tens of mV, www.belling.com.cn Belling Proprietary Information.

Increasing the output capacitor's value and decreasing the ESR attenuates the overshoot. Input-Output (Dropout) Voltage A regulator's minimum input-output voltage differential (or dropout voltage) determines the lowest usable supply voltage. In battery-powered systems, this will determine the useful end-of-life battery voltage. Because the BL9110 uses a P-Channel MOSFET pass transistor, the dropout voltage is a function of drain-to-source on resistance [RDS(ON)] multiplied by the load current. Layout Considerations To improve AC performance such as PSRR, output noise, and transient response, it is recommended that the PCB be designed with separate ground planes for VDD and VOUT, with each ground plane connected only at the GND pin of the device. Make VDD and GND lines sufficiently wide. If their impedance is high, noise pickup or unstable operation may result. Connect a capacitor C1 between VDD and GND pin, as close as possible to the pins. Set external components, especially the output capacitor C2, as close as possible to the IC, and make wiring as short as possible.
