MIC5201 150 mA Low Dropout Regulator Features General Description • • • • • • • • • • • • • • The MIC5201 is an efficient linear voltage regulator with very low dropout voltage (typically 17 mV at light loads and 200 mV at 100 mA), and very low ground current (1 mA at 100 mA output), offering better than 1% initial accuracy with a logic compatible on-off switching input. AEC-Q100 for Fixed Option High Output Voltage Accuracy Variety of Output Voltages Ensured 150 mA Output Low Quiescent Current Low Dropout Voltage Extremely Tight Load and Line Regulation Very Low Temperature Coefficient Current and Thermal Limiting Reversed-Battery Protection Load-Dump Protection (Fixed Voltage Versions) Zero Off-Mode Current Logic-Controlled Electronic Enable Available in SOIC-8 and SOT-223 Packages Designed especially for hand-held battery powered devices, the MIC5201 can be switched by a CMOS enable signal. This enable control may be connected directly to VIN if unneeded. When disabled, power consumption drops nearly to zero. The ground current of the MIC5201 increases only slightly in dropout, further prolonging battery life. Key MIC5201 features include current limiting, overtemperature shutdown, and protection against reversed battery. The MIC5201 is available in several fixed voltages and accuracy configurations. It features the same pinout as the LT1121 with better performance. Other options are available; contact Microchip for details.

Note 1: The maximum allowable power dissipation is a function of the maximum junction temperature, TJ(MAX), the junction-to-ambient thermal resistance, θJA, and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperature is calculated using: P(MAX) = (TJ(MAX) – TA) ÷ θJA.

Devices are ESD sensitive. Handling precautions recommended. Output voltage temperature coefficient is defined as the worst-case voltage change divided by the total temperature range. Regulation is measured at constant junction temperature using low duty cycle pulse testing. Parts are tested for load regulation in the load range from 0.1 mA to 150 mA. Changes in output voltage due to heating effects are covered by the thermal regulation specification. Dropout Voltage is defined as the input to output differential at which the output voltage drops 2% below its nominal value measured at 1V differential. Ground pin current is the regulator quiescent current plus pass transistor base current. The total current drawn from the supply is the sum of the load current plus the ground pin current. Thermal regulation is defined as the change in output voltage at a time “t” after a change in power dissipation is applied, excluding load or line regulation effects. Specifications are for a 150 mA load pulse at VIN = 26V for fixed and VIN = 16V for adjustable at t = 10 ms. Design guidance only. Not production tested.

The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable junction temperature and the thermal resistance from junction to air (i.e., TA, TJ, JA). Exceeding the maximum allowable power dissipation will cause the device operating junction temperature to exceed the maximum +85°C rating. Sustained junction temperatures above +85°C can impact the device reliability.  2017 - 2022 Microchip Technology Inc. and its subsidiaries DS20005718D-page 5 MIC5201 2.0 Note: TYPICAL PERFORMANCE CURVES The graphs and tables provided following this note are a statistical summary based on a limited number of samples and are provided for informational purposes only.

Resistor values are not critical because ADJ (adjust) has a high impedance, but for best results use resistors of 470 kΩ or less. 4.1 Noise Reduction Capacitors Fixed Application. Adjustable regulators require two resistors to set the output voltage. See Figure 4-2. VIN Input Capacitors On adjustable devices, a capacitor from ADJ to GND will decrease high-frequency noise on the output. See Figure 4-3. EN GND 4.2 Output Capacitors A 1 μF capacitor is recommended between the MIC5201 output and ground to prevent oscillations due to instability. Larger values serve to improve the regulator’s transient response. Most types of tantalum or aluminum electrolytics will be adequate; film types will work, but are costly and therefore not recommended. Many aluminum electrolytics have electrolytes that freeze at about –30°C, so solid tantalums are recommended for operation below –25°C. The important parameters of the capacitor are an effective series resistance of about 5Ω or less and a resonant frequency above 500 kHz. The value of this capacitor may be increased without limit. At lower values of output current, less output capacitance is required for output stability. The capacitor can be reduced to 0.47 μF for current below 10 mA or 0.33 μF for currents below 1 mA. FIGURE 4-3: 4.4 Decreasing Output Noise. Minimum Load The MIC5201 will remain stable and in regulation with no load unlike many other voltage regulators. This is especially important in CMOS RAM keep-alive applications. 4.5 Dual-Supply Systems When used in dual supply systems where the regulator load is returned to a negative supply, the output voltage must be diode clamped to ground. 4.6 Thermal Considerations Layout The MIC5201-x.xYM (8-pin surface mount package) has the following thermal characteristics when mounted on a single layer copper-clad printed circuit board. TABLE 4-1: THERMAL CHARACTERISTICS PCB Dielectric θJA FR4 160ºC/W Ceramic 120ºC/W Multilayer boards having a ground plane, wide traces near the pads, and large supply bus lines provide better thermal conductivity. The “worst case” value of 160°C/W assumes no ground plane, minimum trace widths, and a FR4 material board.

At an ambient temperature of +55°C, the device may safely dissipate 440 mW. These power levels are equivalent to a die temperature of +85°C, the recommended maximum temperature for non-military grade silicon integrated circuits.
