NCP2860 300 mA Very Low Noise, Low Dropout Linear Regulator The NCP2860 is a low noise, low dropout linear regulator that is offered with an output voltage of 2.77 V and 3.0 V. It supplies 300 mA from 3.0 V to 6.0 V input. If wished, the “SET’’ pin enables to adjust the output voltage level that then depends on the voltage applied to this pin. The excellent performances that the NCP2860 features in terms of transient responses, PSRR and noise, make it an ideal solution for audio applications (e.g. audio amplifier drivers). http://onsemi.com MARKING DIAGRAM Features • • • • • • • • • 8 High Output Current (300 mA Max) Low Output Voltage Noise: 60 µVrms Low Dropout (150 mV @ Iout = 300 mA) Thermal Overload and Short Circuit Protections Very Low Consumption in Shutdown Mode (10 nA) High Power Supply Rejection Ratio (60 dB @ 1.0 kHz) FAULT Indicator Programmable Output Voltage Soft Start Micro8 DM SUFFIX CASE 846A 8 LCx AYW 1 1 x = Z for NCP260DM277 3 for NCP2860DM300 = Assembly Location = Year = Work Week A Y W Typical Applications • Cellular Phone • Handheld Instruments PIN CONNECTIONS IN FAULT OUT 1 8 FAULT IN 2 7 STDWN GND 3 6 N.C.

Refer to the “output voltage setting’’ paragraph if you need to program another value. 6 N.C. This pin is non–connected. 7 STDWN 8 FAULT “OUT’’ is the regulator output. A low ESR, bypass capacitor should be connected for stable operation. “IN’’ is the supply input that is connected to the power source (up to 6.0 V). Bypass with a 2.2 µF capacitor. If the “STDWN’’ pin is low, the circuit enters the shutdown mode. The “FAULT’’ terminal is a high impedance, open drain output. If the circuit is out of regulation, the voltage pin goes low. Otherwise (normal operation or shutdown mode), this pin is high impedance. Connect the pin to ground, if unused.

Shutdown/Power–Up http://onsemi.com 8 45 50 45 50 NCP2860 DETAILED OPERATING DESCRIPTION Internal Pass Transistor The NCP2860 incorporates a 0.5 Ω typical P–channel MOSFET pass transistor. The P–channel MOSFET requires no drive current and then compared to the PNP based regulators, this solution drastically reduces the quiescent current and associated losses. If the output voltage is directly applied to the “SET’’ pin, Vout = Vref = 1.244 V. Vout OUT Shutdown Block The circuit turns into shutdown mode when the shutdown pin is in low state. In this mode, the internal biasing current sources are disconnected so that the pass transistor is off and the consumption reduced to a minimum value. Practically, the shutdown consumption is in the range of 10 nA. When this function is unused, “IN’’ is generally applied to the shutdown pin. R1 SET R2 NCP2860 Regulation The circuit incorporates a transconductance error amplifier. The error amplifier output varies in response to load and input voltage variations to control the pass transistor current so that the “OUT’’ pin delivers the wished voltage. No compensation capacitor is required. Current Limitation The NCP2860 incorporates a short circuit protection that prevents the pass transistor current from exceeding 465 mA typically. The current limit is set to 220 mA during the start–up phase. Thermal Protection The thermal protection protects the die against excessive overheating. Practically, when the junction temperature exceeds 170°C for the 2.77 V option and 150°C for the 3.0 V option, an internal thermal sensor sends a logical signal to the shutdown block so that the circuit enters the shutdown mode. Once the die has cooled enough (typically 30°C), the circuit enters a new working phase. Fault Detection Circuitry The circuit detects when the input–output differential voltage is too low to ensure a correct load and line regulation at the output. The input–output differential threshold scales proportionally with the load current to be always just higher than the dropout. When the circuit detects a fault condition, an internal switch connects “FAULT’’ to ground. In normal operation, the “FAULT’’ terminal is an open–drain–N–channel MOSFET and if a pull–up resistor is connected between “OUT’’ and “FAULT’’, “FAULT’’ goes high. The pull–up resistor is generally selected in the range of 100 kΩ to minimize the current consumption. Output Voltage Setting The output voltage is set to 2.77 V (or 3.0 V) if the “SET’’ pin is grounded. It can also be programmed to a different value. To do so, a portion of the output voltage must be applied to the “SET’’ pin. If a (R1, R2) resistors divider is used, then: Vout = (1 + R1/R2) * Vref Therefore, as Vref typically equals 1.244 V: Vout = 1.244 * (1 + R1/R2). Application Information It is recommended to use 2.2 F capacitors on the input and on the output of the NCP2860. Capacitor type is not very critical. Simply the ESR should be lower than 0.5 Ω to ensure a stable operation over the temperature and output current ranges. It could be convenient to increase the capacitor size and its quality (lower ESR) only if it was necessary to further improve the noise performances, the Power Supply Rejection Ratio or the fast transient response. Now if R1 and R2 are high impedance resistors, the leakage current that is absorbed by the “SET’’ pin, may have to be taken into account as follows: Vout = [1.244 * (1 + R1/R2)] + (R1*Ilk) where Ilk is the “SET’’ pin leakage current. http://onsemi.com 9 NCP2860 IN FAULT (2) (8) R3 100 k Fault Detect Error Amplifier BANDGAP STDWN – + Drive and Current Limiting SHUTDOWN Rint1 (7) Feedback Selection BATTERY Thermal Sensor C1 2.2 µF OUT OUTPUT BUFFER (1,4) R1 Rint2 SET C2 2.2 µF (5) R2 GND (3) Figure 18.
