300mA High Speed LDO Regulator, Low ESR Capacitance
Compatible, with On/Off Switch
LM6219-3.3N5
General Description
The LM6219-3.3N5 is highly accurate and low noise CMOS LDO voltage regulator. 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.

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.

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.
