LDO

Description

The LDO module describes a converter structure, where a linear low-dropout regulator is placed between capacitor and load to convert the capacitor voltage to a fixed output voltage (i.e., Vout = X) by dissipating the difference between input/output voltage as waste heat (i.e., Eout = Vout/Vcap). In this configuration, there is no converter between harvester and capacitor (i.e., Vin = Vcap, Ein = 1).

Additionally, this converter module can optionally model a hysteresis behavior, where the output is switched on/off at pre-defined voltage thresholds.

Parameters

Parameter	man./opt.	Value	Description
v_out	m	Voltage in V	Output voltage of LDO
i_quiescent	o	Current in A	Quiescent current if output enabled (Default: 0)
i_quiescent_off	o	Voltage in V	Quiescent current if output disabled (Default: i_quiescent)
enable_hyst	o	Boolean	Define whether hysteresis behavior should apply (Default: False)
v_high	o*	Voltage in V	Turn-on hysteresis threshold
v_low	o*	Voltage in V	Turn-off hysteresis threshold
*Mandatory if enable_hyst = True
