The low dropout voltage extends the battery operating lifetime. It also permits high currents in small packages when operated with minimum VIN – VOUT differentials. The MCP1701 has a tight tolerance output voltage regulation of ±0.5% (typical) and very good line regulation at ±0.2%. The LDO output is stable when using only 1 µF of output capacitance of either tantalum or aluminum-electrolytic style capacitors. The MCP1701 LDO also incorporates short-circuit protection to ensure maximum reliability. Package options include the 3-Pin SOT-23A, 3-Pin SOT-89 and 3-Pin TO-92.

MCP1701 3.0 PIN DESCRIPTIONS The descriptions of the pins are listed in Table 3-1. TABLE 3-1: PIN FUNCTION TABLE Pin No. SOT-23A Pin No. SOT-89 Pin No. TO-92 Name 1 1 1 GND Ground terminal 2 3 3 VOUT Regulated voltage output 3 2 2 VIN Unregulated supply input 3.1 Ground Terminal (GND) Regulator ground. Tie GND to the negative side of both the output and the input capacitor. Only the LDO bias current (2 µA, typical) flows out of this pin, as there is no high current. The LDO output regulation is referenced to this pin. Minimize voltage drops between this pin and the negative side of the load. 3.2 Regulated Voltage Output (VOUT) Connect VOUT to the positive side of the load and the positive terminal of the output capacitor. The positive side of the output capacitor should be located as close as possible to the LDO VOUT pin. The current flowing out of this pin is equal to the DC load current. 2004 Microchip Technology Inc. Function 3.3 Unregulated Supply Input (VIN) Connect the input supply voltage and the positive side of the input capacitor to VIN. Like all low dropout linear regulators, low source impedance is necessary for the stable operation of the LDO. The amount of capacitance required to ensure low source impedance will depend on the proximity of the input source capacitors or battery type. The input capacitor should be located as close as possible to the VIN pin. For most applications, 1 µF of capacitance will ensure stable operation of the LDO circuit. For applications that have load currents below 100 mA, the input capacitance requirement can be lowered. The type of capacitor used can be ceramic, tantalum or aluminum-electrolytic. The low ESR characteristics of the ceramic will yield better noise and PSRR performance at high frequencies. The current flow into this pin is equal to the DC load current, plus the LDO bias current (2 µA, typical). DS21874A-page 9 MCP1701 4.0 DETAILED DESCRIPTION The MCP1701 is a low quiescent current, precision, fixed-output voltage LDO. Unlike bipolar regulators, the MCP1701 supply current does not increase proportionally with load current. 4.1 Output Capacitor A minimum of 1 µF output capacitor is required. The output capacitor should have an effective series resistance (esr) greater than 0.1Ω and less than 5Ω, plus a resonant frequency above 1 MHz. Larger output capacitors can be used to improve supply noise rejection and transient response. Care should be taken when increasing COUT to ensure that the input impedance is not high enough to cause high input impedance oscillation. 4.2 Input Capacitor A 1 µF input capacitor is recommended for most applications when the input impedance is on the order of 10Ω. Larger input capacitance may be required for stability when operating from a battery input, or if there is a large distance from the input source to the LDO. When large values of output capacitance are used, the input capacitance should be increased to prevent high source impedance oscillations. 4.3 Overcurrent The MCP1701 internal circuitry monitors the amount of current flowing through the P-channel pass transistor. In the event of a short-circuit or excessive output current, the MCP1701 will act to limit the output current.

MCP1701 5.0 THERMAL CONSIDERATIONS 5.1 Power Dissipation The amount of power dissipated internal to the LDO linear regulator is the sum of the power dissipation within the linear pass device (P-channel MOSFET) and the quiescent current required to bias the internal reference and error amplifier. The internal linear pass device power dissipation is calculated as shown in Equation 5-1. EQUATION 5-1: PD (Pass Device) = (VIN – VOUT) x IOUT The internal power dissipation, which is due to the bias current for the LDO internal reference and error amplifier, is calculated as shown in Equation 5-2. EQUATION 5-2: PD (Bias) = VIN x IGND The total internal power dissipation is the sum of PD (Pass Device) and PD (Bias). To determine the junction temperature of the device, the thermal resistance from junction-to-ambient must be known. The 3-pin SOT-23 thermal resistance from junction-to-air (RθJA) is estimated to be approximately 335°C/W. The SOT-89 RθJA is estimated to be approximately 52°C/W when mounted on 1 square inch of copper. For the TO-92, RθJA is estimated to be 131.9°C/W. The RθJA will vary with physical layout, airflow and other application-specific conditions. The device junction temperature is determined by calculating the junction temperature rise above ambient, then adding the rise to the ambient temperature. EQUATION 5-5: T J = P D MAX × R θJA + T A T J = 116.0 milliwatts × 335°C/W + 55°C T J = 93.9°C EQUATION 5-6: EQUATION 5-3: PTOTAL = PD (Pass Device) + PD (Bias) For the MCP1701, the internal quiescent bias current is so low (2 µA, typical) that the PD (Bias) term of the power dissipation equation can be ignored. The maximum power dissipation can be estimated by using the maximum input voltage and the minimum output voltage to obtain a maximum voltage differential between input and output. The next step would be to multiply the maximum voltage differential by the maximum output current.

DS21874A-page 17 MCP1701 NOTES: DS21874A-page 18 2004 Microchip Technology Inc. Note the following details of the code protection feature on Microchip devices: • Microchip products meet the specification contained in their particular Microchip Data Sheet. • Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the intended manner and under normal conditions. • There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip's Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. • Microchip is willing to work with the customer who is concerned about the integrity of their code. • Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.” Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our products.
