It offers low output noise, high ripple rejection ratio, low dropout and very fast turn-on times. Internally LM6219-3.3N5 includes a reference voltage source, error amplifiers, driver transistors, current limiters and phase compensators. The current limiter’s foldback circuit also operates as a short protect for the output current limiter and the output pin. The output voltage is set by laser trimming. LM6219-3.3N5 is fully compatible with low ESR ceramic capacitors, reducing cost and improving output stability. This high level of stability is maintained even during frequent load fluctuations, due to the excellent transient response performance and high PSRR achieved across a broad range of frequencies. The CE function allows the output of regulator to be turned off, resulting in greatly reduced power consumption. The LM6219-3.3N5 is available in SOT-23-5L package.

Spec. No. : C150N5 Issued Date : 2013.08.30 Revised Date : 2015.05.11 Page No. : 6/9 Operational Explanation ●Output Voltage Control The voltage divided by resistors R1 & R2 is compared with the internal reference voltage by the error amplifier. The P-channel MOSFET, which is connected to the VOUT pin, is then driven by the subsequent output signal. The output voltage at the VOUT pin is controlled and stabilized by a system of negative feedback. The current limit circuit and short protect circuit operate in relation to the level of output current. Further, the IC's internal circuitry can be shutdown via the CE pin's signal ●Low ESR Capacitors With the LM6219-3.3N5, a stable output voltage is achievable even if used with low ESR capacitors as a phase compensation circuit is built-in. In order to ensure the effectiveness of the phase compensation, we suggest that an output capacitor (CL) is connected as close as possible to the output pin (VOUT) and the VSS pin. Please use an output capacitor with a capacitance value of at least 1.0μF. Also, please connect an input capacitor (CIN) of 1.0μF between the VIN pin and the VSS pin in order to ensure a stable power input. Stable phase compensation may not be ensured if the capacitor runs out capacitance when depending on bias and temperature. In case the capacitor depends on the bias and temperature, please make sure the capacitor can ensure the actual capacitance. ●Current Limiter, Short-Circuit Protection The LM6219-3.3N5 includes a combination of a fixed current limiter circuit & a foldback circuit, which aid the operations of the current limiter and circuit protection. When the load current reaches the current limit level, the fixed current limiter circuit operates and output voltage drops. As a result of this drop in output voltage, the foldback circuit operates, output voltage drops further and output current decreases. When the output pin is shorted, a current of about 50mA flows. ●CE Pin The IC's internal circuitry can be shutdown via the signal from the CE pin with the LM6219-3.3N5. In shutdown mode, output at the VOUT pin will be pulled down to the VSS level via R1 & R2. The operational logic of the IC's CE pin is selectable (please refer to the selection guide). Although the CE pin is equal to an inverter input with CMOS hysteresis, with either the pull-up or pull-down options, the CE pin input current will increase when the IC is in operation. We suggest that you use this IC with either a VIN voltage or a VSS voltage input at the CE pin. If this IC is used with the correct specifications for the CE pin, the operational logic is fixed and the IC will operate normally. However, supply current may increase as a result of through current in the IC's internal circuitry. LM6219-3.3N5 CYStek Product Specification CYStech Electronics Corp. Spec. No. : C150N5 Issued Date : 2013.08.30 Revised Date : 2015.05.11 Page No. : 7/9 NOTES ON USE 1. For temporary, transitional voltage drop or voltage rising phenomenon, the IC is liable to malfunction should the ratings be exceeded. 2. Where wiring impedance is high, operations may become unstable due to noise and/or phase lag depending on output current. Please keep the resistance low between VIN and VSS wiring in particular. 3. Please wire the input capacitor (CIN) and the output capacitor (CL) as close to the IC as possible. 4. The IC is controlled with constant current start-up. Start-up sequence control is requested to draw a load current after even nominal output voltage rising up the output voltage. 5. CYS places an importance on improving our products and their reliability. We request that users incorporate fail-safe designs and post-aging protection treatment when using CYS’s products in their systems. LM6219-3.3N5 CYStek Product Specification CYStech Electronics Corp.
