DS9080-07 May 2018 RT9080 Functional Block Diagram VIN (without sense function) Current/Thermal Sense GND SNS (with sense function) + - EN Bandgap Reference VOUT R1 EN R2 Operation Basic Operation Enable The RT9080 is a low quiescent current linear regulator designed especially for low external components system. The input voltage range is from 1.2V to 5.5V. The RT9080 delivers the output power when it is set to enable state. When it works in disable state, there is no output power and the operation quiescent current is almost zero. The minimum required output capacitance for stable operation is 1μF effective capacitance after consideration of the temperature and voltage coefficient of the capacitor. Output Transistor The RT9080 builds in a P-MOSFET output transistor which provides a low switch-on resistance for low dropout voltage applications. Error Amplifier The Error Amplifier compares the internal reference voltage with the output feedback voltage from the internal divider, and controls the Gate voltage of P-MOSFET to support good line regulation and load regulation at output voltage.

DS9080-07 May 2018 Current-Limit Protection The RT9080 provides current limit function to prevent the device from damages during over-load or shorted-circuit condition. This current is detected by an internal sensing transistor. Over-Temperature Protection The over-temperature protection function will turn off the P-MOSFET when the junction temperature exceeds 150°C (typ.), and the output current exceeds 80mA. Once the junction temperature cools down by approximately 20°C, the regulator will automatically resume operation. is a registered trademark of Richtek Technology Corporation. www.richtek.com 3 RT9080 Absolute Maximum Ratings         (Note 1) VIN, VOUT, SNS, EN to GND ------------------------------------------------------------------------------------------VOUT to VIN ---------------------------------------------------------------------------------------------------------------Power Dissipation, PD @ TA = 25°C TSOT-23-5 ------------------------------------------------------------------------------------------------------------------ZQFN-4L 1x1 (ZDFN-4L 1x1) -------------------------------------------------------------------------------------------Package Thermal Resistance (Note 2) TSOT-23-5, θJA ------------------------------------------------------------------------------------------------------------TSOT-23-5, θJC ------------------------------------------------------------------------------------------------------------ZQFN-4L 1x1 (ZDFN-4L 1x1), θJA -------------------------------------------------------------------------------------ZQFN-4L 1x1 (ZDFN-4L 1x1), θJC ------------------------------------------------------------------------------------Lead Temperature (Soldering, 10 sec.) ------------------------------------------------------------------------------Junction Temperature ----------------------------------------------------------------------------------------------------Storage Temperature Range -------------------------------------------------------------------------------------------ESD Susceptibility (Note 3) HBM (Human Body Model) ---------------------------------------------------------------------------------------------- Recommended Operating Conditions    −0.3V to 6.5V −6.5V to 0.3V 0.43W 0.44W 230.6°C/W 21.8°C/W 226°C/W 43°C/W 260°C 150°C −65°C to 150°C 2kV (Note 4) Input Voltage, VIN --------------------------------------------------------------------------------------------------------- 1.2V to 5.5V Junction Temperature Range -------------------------------------------------------------------------------------------- −40°C to 125°C Ambient Temperature Range -------------------------------------------------------------------------------------------- −40°C to 85°C Electrical Characteristics (VOUT + 1 < VIN < 5.5V, TA = 25°C, unless otherwise specified) Parameter Output Voltage Range Symbol Test Conditions VOUT DC Output Accuracy ILOAD = 1mA Min Typ Max Unit 0.8 -- 3.3 V 2 -- 2 % 0.8V  VOUT  1.05V (TSOT-23-5) -- 1.05 1.33 0.8V  VOUT  1.05V (ZQFN-4L 1x1) -- 1.05 1.63 1.05V  VOUT  1.2V -- 0.8 1.13 1.2V  VOUT  1.5V -- 0.71 1.03 1.5V  VOUT  1.8V -- 0.57 0.93 1.8V  VOUT  2.1V -- 0.57 0.83 2.1V  VOUT  2.5V -- 0.41 0.73 2.5V  VOUT  3V -- 0.36 0.63 3V  VOUT -- 0.31 0.53 ILOAD = 0mA, VOUT  5.5V VIN  VOUT + VDROP -- 2 4 A Shutdown GND Current (Note 6) VEN = 0V -- 0.1 0.5 A Shutdown Leakage Current (Note 6) VEN = 0V, VOUT = 0V -- 0.1 0.5 A Dropout Voltage (ILOAD = 600mA) (Note 5) VCC Consumption Current VDROP IQ Copyright © 2018 Richtek Technology Corporation.

DS9080-07 May 2018 RT9080 Application Information Enable The RT9080 has an EN pin to turn on or turn off the regulator, When the EN pin is in logic high, the regulator will be turned on. The shutdown current is almost 0μA typical. The EN pin may be directly tied to VIN to keep the part on. The Enable input is CMOS logic and cannot be left floating. Adjustable Output Voltage Setting Because of the small input current at the SNS pin, the RT9080N with SNS pin also can work as an adjustable output voltage LDO. Figure 3 gives the connections for the adjustable output voltage application. The resistor divider from VOUT to SNS sets the output voltage when in regulation. The voltage on the SNS pin sets the output voltage and is determined by the values of R1 and R2. In order to keep a good temperature coefficient of output voltage, the values of R1 and R2 should be selected carefully to ignore the temperature coefficient of input current at the SNS pin. A current greater than 50μA in the resistor divider is recommended to meet the above requirement. The adjustable output voltage can be calculated using the formula given in equation 1 : VOUT  R1 + R2  VSNS (1) R2 where VSNS is determined by the output voltage selections in the ordering information of the RT9080N. The maximum adjustable output voltage can be as high as input voltage deducted by the dropout voltage. When we choose 51kΩ and 16kΩ as R1 and R2 respectively, and select a 0.8V output at SNS pin, the Copyright © 2018 Richtek Technology Corporation. All rights reserved. DS9080-07 May 2018 adjustable output voltage will be set to around 3.35V. Its temperature coefficient in Figure 4 is still perfect in such kind of application. Output Voltage vs. Temperature 3.35 3.34 Output Voltage (V) Like any low dropout linear regulator, the RT9080's external input and output capacitors must be properly selected for stability and performance. Use a 1μF or larger input capacitor and place it close to the IC's VIN and GND pins. Any output capacitor meeting the minimum 1mΩ ESR (Equivalent Series Resistance) and effective capacitance larger than 1μF requirement may be used. Place the output capacitor close to the IC's VOUT and GND pins. Increasing capacitance and decreasing ESR can improve the circuit's PSRR and line transient response. 3.33 3.32 3.31 3.30 3.29 ILOAD = 1mA 3.28 -50 -25 0 25 50 75 100 125 Temperature (°C) Figure 4. Temperature Coefficient of Adjustable Output Voltage The minimum recommended 50μA in the resistor divider makes the application no longer an ultra low quiescent LDO. Figure 5 is another fine adjustable output voltage application can keep the LDO still operating in low power consumption. The fine tune range is recommended to be less than 50mV (R1 ≤ 91kΩ) in order to keep a good temperature coefficient of the output voltage. RT9080N VIN VOUT 1µF R1 SNS 56pF/NC 1µF EN GND Figure 5. Fine Adjustable Output Voltage Application Circuit There isn't extra current consumption in the above application. But the temperature coefficient of output voltage will be degraded by the input current at SNS pin. If the tuning range is larger than 50mV, a compensation capacitor (56pF) is required to keep the stability of output voltage. The fine adjustable output voltage is calculated using the formula given in equation2 : VOUT  VSNS + ISNS  R1 (2) is a registered trademark of Richtek Technology Corporation. www.richtek.com 11 RT9080 where ISNS is the input Current at SNS pin (typical 550nA at room temperature) and VSNS is determined by the output voltage selections in the ordering information of the RT9080N. The maximum power dissipation depends on the operating ambient temperature for fixed T J(MAX) and thermal resistance, θJA. The derating curve in Figure 6 allows the designer to see the effect of rising ambient temperature on the maximum power dissipation. Current Limit Thermal Considerations For continuous operation, do not exceed absolute maximum junction temperature. The maximum power dissipation depends on the thermal resistance of the IC package, PCB layout, rate of surrounding airflow, and difference between junction and ambient temperature. The maximum power dissipation can be calculated by the following formula : 0.6 Maximum Power Dissipation (W)1 The RT9080 contains an independent current limiter, which monitors and controls the pass transistor's gate voltage, limiting the output current to 1.1A (typ.). The current limiting level is reduced to around 0.6A named fold-back current limit when the output voltage is further decreased. The output can be shorted to ground indefinitely without damaging the part.

Derating Curve of Maximum Power Dissipation PD(MAX) = (TJ(MAX) − TA) / θJA where TJ(MAX) is the maximum junction temperature, TA is the ambient temperature, and θJA is the junction to ambient thermal resistance. For recommended operating condition specifications the maximum junction temperature is 125°C and TA is the ambient temperature. The junction to ambient thermal resistance, θJA, is layout dependent. For TSOT-23-5 package, the thermal resistance, θJA, is 230.6°C/W on a standard JEDEC 51-7 four-layer thermal test board. For ZQFN-4L 1x1 (ZDFN-4L 1x1) package, the thermal resistance, θJA, is 226°C/W on a two-layer Richtek evaluation board. The maximum power dissipation at TA = 25°C can be calculated by the following formula : PD(MAX) = (125°C − 25°C) / (230.6°C/W) = 0.43W for TSOT-23-5 package PD(MAX) = (125°C − 25°C) / (226°C/W) = 0.44W for ZQFN-4L 1x1 (ZDFN-4L 1x1) package Copyright © 2018 Richtek Technology Corporation.
