MIC5210 Dual 150 mA LDO Regulator Features General Description • • • • • • • • • • • The MIC5210 is a dual linear voltage regulator with very low dropout voltage (typically 10 mV at light loads and 140 mV at 100 mA), very low ground current (225 µA at 10 mA output), and better than 1% initial accuracy. It also features individual logic-compatible enable/shutdown control inputs. Mini 8 MSOP Package Up to 150 mA per Regulator Output Low Quiescent Current Low Dropout Voltage Wide Selection of Output Voltages Tight Load and Line Regulation Low Temperature Coefficient Current and Thermal Limiting Reversed Input Polarity Protection Zero Off-Mode Current Logic-Controlled Electronic Enable Both regulator outputs can supply up to 150 mA at the same time as long as each regulator’s maximum junction temperature is not exceeded. Key features include a reference bypass pin to improve its already low-noise performance, reversed-battery protection, current limiting, and overtemperature shutdown. Applications • • • • • • Designed especially for hand-held battery powered devices, the MIC5210 can be switched by a CMOS or TTL compatible logic signal, or the enable pin can be connected to the supply input for 3-terminal operation. When disabled, power consumption drops nearly to zero. Dropout ground current is minimized to prolong battery life.

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 = 16V for t = 10 ms. DS20006096A-page 4  2019 Microchip Technology Inc. MIC5210 TEMPERATURE SPECIFICATIONS (Note 1) Parameters Sym. Min. Typ. Max.

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. Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply when operating the device outside of its operating ratings. 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: PD(max) = (TJ(max) – TA)/θJA. Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown. The θJA of the 8-pin MSOP (MM) is 200°C/W mounted on a PC board (see “Thermal Considerations” section for further details).  2019 Microchip Technology Inc.

Do not leave floating. 8 INA Supply Input A  2019 Microchip Technology Inc. Description DS20006096A-page 9 MIC5210 4.0 APPLICATION INFORMATION 4.1 Enable/Shutdown Forcing EN (enable/shutdown) high (greater than 2V) enables the regulator. EN is compatible with CMOS and TTL logic gates. If the enable/shutdown feature is not required, connect EN to IN (supply input). 4.2 Input Capacitor 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. 4.5 The MIC5210 will remain stable and in regulation with no load (other than the internal voltage divider) unlike many other voltage regulators. This is especially important in CMOS RAM keep-alive applications. A 1 µF capacitor should be placed from IN to GND if there is more than 10 inches of wire between the input and the AC filter capacitor or if a battery is used as the input. 4.6 4.3 4.7 Reference Bypass Capacitor No-Load Stability Dual-Supply Operation 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. Thermal Considerations BYPB (reference bypass) is connected to the internal voltage reference of regulator B. A 470 pF capacitor (CBYP) connected from BYPB to GND quiets this reference, providing a significant reduction in output noise. CBYP reduces the regulator phase margin; when using CBYP, output capacitors of 2.2 µF or greater are generally required to maintain stability. Multilayer boards having a ground plane, wide traces near the pads, and large supply bus lines provide better thermal conductivity. The start-up speed of the MIC5210 is inversely proportional to the size of the reference bypass capacitor. Applications requiring a slow ramp-up of output voltage should consider larger values of CBYP. Likewise, if rapid turn-on is necessary, consider omitting CBYP. For additional heat sink characteristics, please refer to Application Hint 17, “Designing P.C. Board Heat Sinks.” If output noise is not a major concern, omit CBYP and leave BYPB open. 4.4 The MIC5210-xxYMM (8-pin MSOP) has a thermal resistance of 200°C/W when mounted on a FR4 board with minimum trace widths and no ground plane. 4.7.1 THERMAL EVALUATION EXAMPLES For example, at 50°C ambient temperature, the maximum package power dissipation is: EQUATION 4-1: Output Capacitor An output capacitor is required between OUT and GND to prevent oscillation. The minimum size of the output capacitor is dependent upon whether a reference bypass capacitor is used. 1.0 µF minimum is recommended when CBYP is not used. 2.2 µF minimum is recommended when CBYP is 470 pF (see Typical Application Circuit). Larger values improve the regulator’s transient response. The output capacitor value may be increased without limit. The output capacitor should have an ESR (effective series resistance) of about 5Ω or less and a resonant frequency above 1 MHz. Ultralow-ESR capacitors may cause a low-amplitude oscillation and/or underdamped transient response. Most tantalum or aluminum electrolytic capacitors are adequate; film types will work, but are more expensive. Because many aluminum electrolytic capacitors have electrolytes that freeze at about –30°C, solid tantalum capacitors are recommended for operation below –25°C. DS20006096A-page 10 P D  MAX  =  125C – 50C    200C/W  = 375mW If the intent is to operate the 5V version from a 6V supply at the full 150mA load for both outputs in a 50°C maximum ambient temperature, make the following calculation: EQUATION 4-2: P D  EACHREG  =  V IN – V OUT   I OUT +  V IN  I GND   2019 Microchip Technology Inc. MIC5210 EQUATION 4-3: P D  EACHREG  =  6V – 5V   150mA +  6V  2.5mA  = 165mW EQUATION 4-4: P D  BOTHREG  = 2Regulators  165mW = 330mW The actual total power dissipation of 330 mW is below the 375 mW package maximum; therefore, the regulator can be used. Note that both regulators cannot always be used at their maximum current rating. For example, in a 5V input to 3.3V output application at +50°C, if one regulator supplies 150 mA, the other regulator is limited to a much lower current. The first regulator dissipates: EQUATION 4-5: P D =  5V – 3.3V   150mA +  5V  2.5mA  = 267.5mW Then, the load that the remaining regulator can dissipate must not exceed 375 mW – 267.5 mW = 107.5 mW. This means, using the same 5V input and 3.3V output voltage, the second regulator is limited to about 60 mA. Taking advantage of the extremely low-dropout voltage characteristics of the MIC5210, power dissipation can be reduced by using the lowest possible input voltage to minimize the input-to-output voltage drop.  2019 Microchip Technology Inc.
